5.14 Line Decoding 5.14.1 Line Decoding

(1) NRZI (Non return to zero, inverted)

Non return to zero, inverted (NRZI) is a method of mapping a binary signal to a

physical signal for transmission over some transmission media. The two level

NRZI signal has a transition at a clock boundary if the bit being transmitted is a

logical one, and does not have a transition if the bit being transmitted is a logical

zero.

There are two modes:

a. NRZI (Transition occurs for a one)

A 1 is represented by a transition of the physical level, a 0 has no transition.

b. NRZI (Transition occurs for a zero)

A 0 is represented by a transition of the physical level, a 1 has no transition.

(2) Manchester

In telecommunication, Manchester code is a line code in which the encoding of

each data bit has at least one transition and occupies the same time. It is, therefore,

self-clocking, which means that a clock signal can be recovered from the encoded

data.

There are three modes: a. Manchester (Thomas)

A 0 is expressed by a low-to-high transition, a 1 by high-to-low transition.

b. Manchester (IEEE802.3)A 1 is expressed by a low-to-high transition, a 0 by

high-to-low transition.

c. Differential Manchester

A 1 bit is indicated by making the first half of the signal equal to the last half of

the previous bit's signal i.e. no transition at the start of the bit-time. A '0' bit is

indicated by making the first half of the signal opposite to the last half of the

previous bit's signal i.e. a zero bit is indicated by a transition at the beginning of

the bit-time. In the middle of the bit-time there is always a transition, whether

from high to low, or low to high. A reversed scheme is possible, and no

advantage is given by using either scheme.

(3) Biphase Mark

The biphase mark code (also called FM1 code) is a type of encoding for binary

data streams. When a binary data stream is sent without modification via a

channel, there can be long series of logical ones or zeros without any transitions

which makes clock recovery and synchronization difficult. When encoding, the

symbol rate must be twice the bitrate of the original signal. Every bit of the

original data is represented as two logical states which, together, form a bit.

symbol rate must be twice the bitrate of the original signal. Every bit of the

original data is represented as two logical states which, together, form a bit.

(4) AMI (Alternate Mark Inversion)

There are four modes:

a. AMI (Standard)

AMI (Alternate Mark Inversion) is a synchronous clock encoding technique that

uses bipolar pulses to represent logical 1 value. It is therefore a three level

system. A logical 0s is represented by no symbol, and a logical 1 is represented

by pulses of alternating polarity.

b. AMI (B8ZS) :Bipolar-8-Zero Substitution

If 1 is +, 00000000 is represented to 000+-0-+

1 is -, 00000000 is represented to 000-+0+-

c. AMI (HDB3) :High Density Bipolar 3

The HDB3 code is a bipolar signaling technique (i.e. relies on the transmission of

both positive and negative pulses). It is based on Alternate Mark Inversion

(AMI), but extends this by inserting violation codes whenever there is a run of 4

or more 0's. This and similar (more complex) codes have replaced AMI in

modern distribution networks. The encoding rules follow those for AMI, except

that sequences of four consecutive 0’s are encoding using a special "violation"

bit. This bit has the same polarity as the last 1-bit which was sent using the AMI

encoding rule. The purpose of this is to prevent long runs of 0's in the data stream

that may otherwise prevent a DPLL from tracking the center of each bit. Such a

code is sometimes called a "run length limited" code, since it limits the runs of

0’s that would otherwise be produced by AMI. One refinement is necessary, to

prevent a dc voltage being introduced by excessive runs of zeros. This

refinement is to encode any pattern of more than four bits as B00V, where B is a

balancing pulse. The value of B is assigned as + or -, so as to make alternate

"V"s of opposite polarity. The receiver removes all Violation pulses, but in

addition a violation preceded by two zeros and a pulse is treated as the "B00V"

pattern and both the violation and balancing pulse are removed from the received

bit stream. This restores the original bit stream.

d. MLT-3：Multilevel Transmission 3

A 0 has no transition, a 1 is represented by a transition (0, +, 0, -).

(4) Pseudoternary

A 1 is always zero, a 0 is represented by a transition (+, -).

(5) CMI (Coded Mark Inversion)

A zero is sent a low to high [01] transition, while a one is sent as either a one [1]

or zero [0] depending on the previous state. If the previous state was high the one

is sent as a zero [0], if it was low the one is sent as a one [1].

6.10 Data Storage

There are three ways to store the captured data: 1.Conventional, 2.Transitional and

3.Qualified.

6.10.1 Conventional Storage

This is the most common way to store the captured data, 1 bit by bit, and the logic

analyzer will stop when its memory buffer is full.

6.10.2 Transitional Storage

The logic analyzer will only store the transitional data (rising or falling) and record

the time duration of the non-transitional data which is also called Time Stamp.

Only the TravelLogic series supports the transitional storage.

(1) Features

a. Long Duration

The TravelLogic logic analyzer only record the transitional data, so the recorded

time can be long duration as long as the data is not in transition.

b. All Channels available

All channels are available for the transitional storage for the TravelLogic series.

c. Captured data will not be lost even interrupted

The captured data will not be lost even when the logic analyzer is stopped when

capturing data.

d. Display the used memory buffer

The LA Viewer will display the percentage of the memory buffer is being used.

(2) How to use the Transitional Storage

Click Hardware Settings ( ) on Toolbar (or Device menu) to show the Hardware Settings dialog box below.

Quick tips:

a. If there many transitions in the captured data, then do NOT use the Transitional

Storage.

b. The maximum memory buffer of each TravelLogic model will be set as default,

not available for change. Also, Only the transitional data of the channels on the

LA Viewer window can be stored.

c. The LA Viewer will set the trigger position in percentage, which means the data

after the trigger position as a percentile of the total captured data. The trigger

cursor can’t be input (moved) on the waveform window as the conventional

storage.

d. The Pre-Trigger is not available for the Transitional Storage.

6.10.3 Qualified Storage

The Qualified Storage is only available for the Transitional Storage. It works as a

filter to store data (in read or write status) in the Transitional Storage to further

expand the efficiency of the memory buffer. The Qualified Storage is only

available for the TravelLogic series.

(1) Features

a. Save/Don’t Save qualified data

You may set conditions to save or not to save the qualified data.

b. Available for multi channels or the bus decodes.

c. Multi-conditions

Conditions can be 1, , 0, rising, falling, or transition.

d. Continuous time

The time of the waveform of the qualified storage is continuous.

(2) Qualified Storage Settings

a. Disable Qualified storage

The Qualified storage is

disabled when the column

checked.

b. Parameter

Double click on Value to

show the conditions (rising,

falling, or transition).

c. Save/Don’t Save

Click to save or don’t save the qualified data.

Chapter 7 Digital Data Logger

7.1 How to use Digital Data Logger? 7.1.1 Use time

This feature is only available in TravelLogic Series.

7.1.2 Start the Digital Data Logger

It is able to record the acquired data for a long time as a log file xxx.log and

independent of the LA Viewer. To use the record model only to record the

transitional data (rising or falling edge), therefore, the overall amount of data

transmitted will decrease because the data don’t change.

You can find and click the Data Logger icon ( ) in the programs (Start\All

Programs\Acute Logic Analyzer\Digital Data Logger) of your PC to show the dialog

box below.

Parameters

(1) File

Enter the file name as xxx.log.

(2) Sampling Rate

In "Hz", can be an integer or decimal number. The maximum value is 50MHz.

(3) Channels

The number of channels recorded.

(4) Auto stop after XX sec.

Stop Data Logger after the time (in seconds).

(5) Time sec.

The time (in seconds) being running Data Logger.

Note: The logged file may lose some data if the sampling rate is high and will

mark in the file. If this occurs, the program will place in the data leakage, marked

“Lose data”.

(6) Filter Setting

You may filter the logged data in the Filter setting dialog below.

Filter conditions are 0：Low、1：High、X：Disable、↑：Low to High、↓：High

to Low、↕：Change. The data of each channel can be saved in any one condition.

(7) Threshold Setting

You may also set the threshold for the data logger.

7.1.3 Data Format

An example of the acquired data, consisting of Information (sampling rate and

format in green box), Time (in decimal number when the edge changes in red box)

and Data (in hexadecimal number in blue box), is shown below. The first data

recording time is not necessarily 0, because the internal counter will start from

power after the count. Therefore, it is normal. If it is found much record time

interval, because data did not change, so do not record data, this is normal.

The sampling rate is 1000Hz, 0000000000026 in the red box denotes the edge

changes at 26/1000th second and 00003FFFF in the blue box denotes the data

value for 36 channels at 26/1000th second. Bit 0 of data for the channel 0.

Chapter 8 Miscellaneous

8.1 Notes

8.1.1 You can run several LA Viewer programs at the same time and if your PC has

enough memory, but the second to open the LA Viewer will only demo mode.

8.1.2 Always connect the logic analyzer’s ground lines to the target system in order to

improve the measurement quality.

8.1.3 Connect the LA2000P’s four pods (pod A, B, C and D) to its four ports (port A, B,

C and D) in their respectively alphabetic order unless you want to check the function

of each pod.

8.1.4 Do NOT connect the LA2000P’s printer round cable to the LA 2000P and the

printer at the same time.

8.1.5 If you use the PCI interface for the LA2000P, insert the LA mainframe into the

PC’s lowest disk slot, so the cables will not interfere with the PC’s CD-ROM drive.

8.1.6 If you use the external trigger for the LA2000P, connect the RG-58A/U (50 Ohm)

coaxial cable with a BNC connector to the LA.

8.1.7 Connect the probe’s ground to the earth ground ONLY, NOT an elevated voltage.

Please refer to the two figures in the next page.

 Prohibition 1:

 Prohibition 2: Electric potential A and B are not equal.

8.2 Tips

8.2.1 Search Next Click Search Pattern on Toolbar, set search patterns and click Search,

then move Cursor B to the trigger cursor position and click Search Next Pattern

button.

8.2.2 Use Create Bus(Signal) to set parameters for group channels or bus.

8.2.3 The LA2164P model has 64 channels; but ONLY 32 channels (CH 0 ~ CH 31)

support 200MHz sample rate, so connect these channels to those signals that are

200MHz from the target system.

8.2.4 Press A-Z key on the keyboard move the selected (key) cursor to the middle of the

Waveform Window.
