Notice Hewlett-Packard to Agilent Technologies Transition This documentation supports a product that previously shipped under the Hewlett- Packard company brand name. The brand name has now been changed to Agilent Technologies. The two products are functionally identical, only our name has changed. The document still includes references to Hewlett-Packard products, some of which have been transitioned to Agilent Technologies.

It uses a synthesized LO to provide accurate frequency tuning and an internal micro-computer to automate controls and provide useful operating features. HP 8566B SPECTRUM ANALYZER The HP 8566B consists of an 85662A Display Section and an 85660B RF Section. Connect the two sections along with the inter-connection cables as shown in the illustration below. Connect interconnection cables as shown: Line Module 85662A Display Section 85660B RF Section Line Module. HP-IB Connector I \ Interconnect Cable Interconnect Cable (85662-60093) (85662-60094) REAR PANEL CONNECTIONS Manual Operation 1 INITIAL POWER ON GENERAL INFORMATION CAUTION Before connecting the line power cords, make sure the appropriate line voltage and line fuse have been selected for both the RF and Display sections of the analyzer. For complete information on line voltage and fuse selection, refer to the HP 8566B Opera- tor’s Handbook. For information on line power cords for a specific country, contact the nearest Hewlett-Packard office. INITIAL POWER ON After making the AC power line connections, the STANDBY lights of both the RF and Display section should be on. As long as the instrument is operating (LINE ON) or in STANDBY, the accuracy specifications of the internal frequency standard will be met. After a cold start, such as on-receipt of instrument, the analyzer requires 24 hours to stabilize prior to meeting specified performance. LINE ON AND STANDBY INSTR CHECK LED Upon LINE ON, the instrument will perform an automatic internal instrument check. If one or both of the red instrument check lights (INST CHECK I and II) remain on after this brief check routine, refer to the chart below to localize the problem. LED On Problem Solution I Digital Storage failure in 85662A Check bus interconnect cable (85662-60094) Check bus interconnect cable (85662-60094) II Interface Failure and check if Al2 board is connected tightly Check if Al5 is connected tightly in 85660B Controller (A15) and that contacts are clean. Calibration In order to meet specified frequency and amplitude accuracy, the analyzer’s calibration must be checked periodi- cally to ensure the highest performance. 2 Manual Operation GENERAL INFORMATION RF INPUT RF INPUT FREQZERO 0 Connect cablec from CAL OUTPUT signal to RF input to perform initial calibration. CAUTION Excessive signal input power will damage the input attenuator and the input mixer. The spectrum analyzer total RF power must not exceed + 30 dBm (1 watt). DC Precaution: The HP 8566B cannot accept DC voltages in 0 dB ATTEN. With 10 dB or greater input attenuation, a maximum of k7V DC can be accepted without damage. A blocking capacitor is recommended at the input when DC is present with an RF signal. Manual Calibration Procedure 1. After instrument has stabilized, press m 2. Press @ 8; this recalls the following stored control settings from the analyzer’s internal memory: Center Frequency = 100 MHz Frequency Span = 2 MHz Reference Level = - 7 dBm Res BW = 1 MHz Scale = 1 dB/Div Marker = Normal 3. Adjust AMPTD CAL for a marker amplitude of - 10 dBm. * 4. Press [1Ic1LLl 9; this recalls the following: Center Frequency = 100 MHz Frequency Span = 0 Hz Reference Level = - 7 dBm Res BW = 30 Hz Scale = 1 dB/Div Sweep Time = 10 Sec. l If connection cable has significant loss, it must be accounted for separately. Manual Operation 3 CRT DISPLAY GENERAL INFORMATION 5. Maximize amplitude response with FREQ ZERO adjustment. Error Correction Routine A 30 second internal error correction routine minimizes uncertainties due to control changes in the analyzer. To start the routine, press (,,,,, W (%?I. A “CORR’D” readout will appear on the left edge of the CRT upon completion of this routine. If the message “Adjust AMPTD CAL” appears in the display, repeat the manual calibration before running the error correction routine again. CRT DISPLAY The analyzer’s CRT display presents the signal response trace and all pertinent measurement data. The active function area names the function under DATA control and shows the function values as they are changed. All the information necessary to scale and reference the graticule is provided.
