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.

GENERAL INFORMATION GENERAL DESCRIPTION
GENERAL INFORMATION
The HP 8566B is a high-performance spectrum analyzer which operates from 100 Hz to 2.5 GHz in the low
frequency band and 2 - 22 GHz in the preselected microwave band. 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:

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.

Interface Failure
Solution
Check bus interconnect cable (85662-60094)
Check bus interconnect cable (85662-60094)
and check if Al2 board is connected tightly
Controller (A15)
Check if Al5 is connected tightly in 85660B
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.

GENERAL INFORMATION RF INPUT
RF INPUT
FREQZERO
c
0
Connect cable 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.

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.

PLOTTER OUTPUT
The trace data, graticule, and annotation on the analyzer’s screen can be directly output via HP-IB to a Hewlett-
Packard plotter (such as the HP 7245A/B, 7240A, 7470A, or 9872C) by pressing the LOWER LEFT key on the
front pane1 of the analyzer.
