Opening the cover voids the warranty. To return a meter to Telewave; complete the RMA request form located on our web site at www.telewave.com, or call 408-929-4400 Option 1 if assistance is needed to compete the RMA.

The meter will not be damaged by mist, fog, or light rain. Wipe the moisture off with a dry cloth.

WARNING: The meter is water resistant, but not water proof. If it appears that any liquid has entered the meter (dropped in water), return the meter to Telewave for an internal inspection.

WARNING: Contact Telewave support at [email protected] or call 408-929-4400 Option 2 if the meter appears to malfunction or is giving obviously incorrect readings. Storage The meter can be stored for long periods of time with no damage. It is recommended to store the meter in the TC44 Case, or it can be wrapped in a cloth and placed into a box or other container.

If the meter is accidently left on or turned on when placed into storage, the power controller will eventually turn off the meter. Even when turned off, the batteries will discharge during storage.

WARNING: Store the meter in a dry, temperature controlled environment. Long term exposure to temperatures outside specification, or moisture may damage the meter.

WARNING: Charge the batteries at least once every six months to prevent battery damage.

CAUTION: Fully charge the batteries after removing the meter from long term storage. Cleaning To clean the wattmeter, put some mild liquid soap onto a soft but moist cloth. Wipe the dirt from the wattmeter with a light touch. Use a rinsed moist towel or a second moist towel to clean any residual soap from the wattmeter. The meter can air dry or be dried with a third soft cloth.

The accessories or optional case can be cleaned using the same procedure as for the meter.

WARNING: Make sure the power supply and USB cable are dry before connecting to AC power. An electrical shock hazard exists if the components are wet when plugged in to an outlet.

WARNING: Do not use more than a few drops of water or soap when cleaning the meter. Excessive water or soap could leak into the meter and may cause damage or a malfunction.

CAUTION: Do not use powder or abrasive soap. These soaps may scratch the case or display cover glass. Scratches or similar damage to the display cover glass are not warrantied.

Copyright © 2018 Telewave, Inc. Page 15 of 29 Specifications subject to change without notice 3 Jul 2018 44D User Manual Calibration Telewave recommends returning the wattmeter to the factory every two years for inspection & calibration. Calibration must be done at Telewave, contact Telewave sales for a quote.

Before each meter is calibrated it will be inspected. A report will be provided detailing any issues found (including battery health test report.) Any deficiencies will be repaired (warranty for free, non-warranty if customer authorized) and then the meter will be calibrated. Unrepaired deficiencies may cause calibration failure. Firmware version will be updated to latest, no charge.

Accuracy is guaranteed as long as the frequency that is measured and the ambient temperature are within the specified range. There are no field offset tables for frequency or temperature.

CAUTION: Accuracy also depends on properly cabling the wattmeter into the circuit to be tested. Carefully follow the instructions for connecting the meter as described below.

To return a meter to Telewave; complete the RMA request form located on our web site at www.telewave.com, or call 408-929-4400 Option 1 if assistance is needed to complete the RMA.

Copyright © 2018 Telewave, Inc. Page 16 of 29 Specifications subject to change without notice 3 Jul 2018 44D User Manual Appendix: Connecting the Meter to the Circuit Concepts RF power will transfer from the source to the destination with the most efficiency when:  The source and load impedance are the same  The source and the load are separated from each other by a cable that has been cut so that the electrical length of that cable is a ½ wavelength increment.

When the cables are ½ electrical wavelength increment long, any reflected energy from a load or source mismatch will arrive at the source 180 degrees out of phase compared to the energy emanating from that source. The reflected energy will cancel a portion of the source energy.

Cutting the cables to the proper length in the LMR environment has the following advantages:  Energy reflected by mismatches is dissipated, rather than bounce back and forth  Power amplifiers and other components will run cooler (less energy to dissipate)  Power meters can more accurately read forward vs. reverse power in the circuit  Impedance mess-matches at an antenna/feed interface are less likely to be masked by the losses encountered with long feed lines.  Inserting a meter into the circuit has less impact on the behavior of the circuit.

To properly connect the wattmeter to the circuit to be tested, the cables used to insert the meter into the circuit should be of a length that is close (within 10%) to an increment of ½ wavelength. These cables are a “Primary Cable” (always need) and a “Secondary Cable” (sometimes need).

When calculating the length of the “primary cable”, subtract 5 inches (12.5 cm) from the length of the cable to allow for the insertion of the wattmeter.

When calculating the length of the “secondary cable”, do NOT subtract any length for the meter. This cable should be an exact ½ wavelength increment in length.

It is suggested to have one or two primary cables built for each band that needs to be tested. For example, a cable built to 159 MHz would cover 144 MHz to 174 MHz. Another cable built for 455 MHz would cover 440 to 470 Mhz. The key is using the same cables in a consistent manner so that the test results are repeatable, and any system changes are noticed during maintenance.

CAUTION: The formulas for calculating the cut length of the cable does not consider the length of any lead wire from a connector on a radio, amplifier, cavity or other device in the RF system. In some situations, the length of internal leads and/or cavity loop lengths may need to be considered and the length of the primary and secondary cables shortened to properly compensate.

Copyright © 2018 Telewave, Inc. Page 17 of 29 Specifications subject to change without notice 3 Jul 2018 44D User Manual Calculating the Primary & Secondary Cable Cut Length The steps to calculate the length of the cables are:

Find the base cable length: (Speed of Light in a vacuum (299,792,458 Meters/Second) divided by (Frequency in Hertz)) Times (Velocity Factor of the cable in %) Times (wave length required… 0.5 for ½ etc.)

Sample = ((299792458/445000000) * 0.85 *0.5) = 0.29 meters or 28.6 cm

Subtract 2 cm for the 2 N Male connectors on the end of the cable: Sample = 28.6 cm minus 2 cm (for two each N Male connectors = 26.6 cm

Subtract 12.5 cm for the meter: Sample = 26.6 cm minus 12.5 cm (the distance across the thru line meter) = 14.1 cm

In this example, the final cut length for the cable would be 14.1 cm.

If a cable is required after the meter (to reach back to the feed line as an example), that cable should be built to ½ wave length without compensating for the meter = 26.6 cm cut length

CAUTION: The samples above are for a ½ wave length cable. The cables can be made longer as needed. Make the cables lengths at a ½ wave length increment: 1.0, 1.5, 2.0, etc. Sample Primary and Secondary Cable Lengths The tables assume that the cables will have N Male connectors at each end, thus 2 cm will be subtracted already for the cable cut length.

Velocity Factor 66% For cables such as: RG-214, RG-213, RG-174, RG-58, and RG-6A

Page 21 of 29 Specifications subject to change without notice 3 Jul 2018 44D User Manual Appendix: RF Sample Port Isolation The “RF Sample Port” provides a simple and safe path to connect test equipment to the circuit under test. The port is bi-directional, meaning that a signal from either direction of the thru line coupler can be monitored, or a signal can be injected into both directions of the thru line coupler.

The Sample Port is passive and has a usable bandwidth from 30 MHz to 1 GHz. The active components of the meter have a narrower bandwidth of 88 MHz to 1 GHz.

The isolation provided by the sample port is consistent at 50 dB +/- 2 dB from 200 MHz up though 1 GHz (the highest frequency supported by the wattmeter.)

Below 200 MHz the isolation begins to increase as shown in the tables below until it reaches a maximum of ~62.5 dB at 30 MHz. The response is detailed below for situations where absolute power levels need to be measured (from the circuit under test) or injected (into the circuit).

Page 25 of 29 Specifications subject to change without notice 3 Jul 2018 44D User Manual Appendix: Special Test Cases Positive Train Control (PTC) Radios For all PTC radios (Base, Wayside or Locomotive) set the radio to transmit a PN9 test pattern while taking a power measurement with the 44D. When in test mode the radio will transmit in all time slots, giving the meter a stable signal to measure.

When a PTC radio is in normal mode, the 44D does not know what or how many time slots have transmit energy; thus only the peak power measurement will be accurate, the average power and calculated values may not be accurate. TETRA Subscriber Radios For all Tetra 1 & 2 subscriber radios (mobile or hand held) create a test talk group that requires all time slots. When testing any subscriber radio in the field, tune the “channel” to this talk group before attempting to take a power measurement. When the radio is transmitting in all time slots, the meter has a stable signal to measure

When a Tetra subscriber radio is in normal mode, the 44D does not know what or how many time slots have transmit energy; thus only the peak power measurement will be accurate, the average power and calculated values may not be accurate.

Tetra base and repeater radios do not need a special talk group, the repeaters always transmit in all time slots. Monitoring an Antenna that follows a TX Combiner The 44D relies on the ability to know the frequency of the signal being measured in order to provide the high absolute accuracy indicated in the specifications. The frequency counter of the 44D may or may not resolve an accurate frequency of any carrier when multiple transmitters are transmitting at the same time (such as the case with a combiner output.)

Even though the meter may calculate an incorrect absolute power measurement when two or more carriers are seen at the same time; the meter still can indicate the health of the system, feedline or antenna. The meter is still able to accurately measure calculated ratios (VSWR/Return Loss.) The meter is also able to measure the difference in average and peal power seen (Crest factor measurement.)

Over time, changes in the “apple to apples” measurements of individual transmitters, the output power reading of the combiner, and the antenna VSWR/return loss – help to indicate and localize problems in a combiner or antenna system.
