WARNING No operator serviceable parts inside. Refer servicing to qualified personnel. To
prevent electrical shock, do not remove covers.
WARNING For continued protection against fire hazard, replace line fuse only with same
type and ratings (type 6.3A/250V). The use of other fuses or materials is
prohibited.
CAUTION Always use the three-prong ac power cord supplied with this instrument.
Failure to ensure adequate earth grounding by not using this cord may cause
instrument damage.
WARNING This is a Safety Class 1 Product (provided with a protective earthing ground
incorporated in the power cord.) The mains plug shall only be inserted in a
socket outlet provided with a protective earth contact. Any interruption of the
protective conductor inside or outside of the instrument is likely to make the
instrument dangerous. Intentional interruption is prohibited.
CAUTION This instrument is designed for use in Installation Category II and Pollution
Degree 2 per IEC 1010 and 664 respectively.
CAUTION Ventilation Requirements: When installing the instrument in a cabinet, the
convection into and out of the instrument must not be restricted. The ambient
temperature (outside the cabinet) must be less than the maximum operating
temperature of the instrument by 4 C for every 100 watts dissipated in the
cabinet. If the total power dissipated in the cabinet is greater than 800 watts,
then forced convection must be used.
WARNING If this instrument is not used as specified, the protection provided by the
equipment could be impaired. This instrument must be used in a normal
condition (in which all means for protection are intact) only.

Surveillance with the HP 71910A
The HP 71910A Wide-Bandwidth Surveillance Receiver provides both signal search and signal
collection capability from 100 Hz to 26.5 GHz. It is optimized for surveillance and signal
monitoring applications. The HP 71910A can be operated in either of the following two
instrument modes:
Spectrum analyzer operation for signal searches
Maximum resolution BW ::::::::::::::::::::::::::::::::::::::::::::::::: 3 MHz
Wide-bandwidth receiver operation for signal collection
IF BW ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: 10 to 100 MHz
Note When you use the wide-bandwidth surveillance receiver, remember that in
spectrum analyzer mode the maximum resolution bandwidth is 3 MHz; it is
not a 100 MHz bandwidth spectrum analyzer.
The receiver's IF and video outputs can be examined by oscilloscopes, demodulators,
digitizers, FFT baseband analyzers, and other instruments.

HP 71910A Option 011
When rst turned on, the wide-bandwidth surveillance receiver operates as a spectrum
analyzer. This allows you to view signals across a large frequency range. Once you've located
a signal, switch to the xed-tuned receiver mode to downconvert the signal.
The downconverted signal is available at the rear panel for processing and analyzing by
external devices. The Option 011 version of the instrument is primarily used as a collection
receiver; it has very limited spectrum analyzer capability due to linear detection and 3 MHz
maximum peak detection bandwidth. (Option 013 adds an HP 70902A to provide a more
complete spectrum analyzer.)
IF outputs are available at the rear panel
In receiver mode, the downconverted signal is available at the instrument's rear panel. The
standard rear-panel output is centered at 321.4 MHz. Option 001 and 002 instruments provide
additional 70 MHz and 140 MHz IF signals respectively. Refer to Chapter 3 for examples of
processing these signals.
v
Demodulated outputs are available at the front panel
The front-panel VIDEO connector provides AM and pulse demodulation. Option 004 provides
additional I/Q outputs and Option 005 provides an additional FM output. Refer to Chapter 3
for examples of processing these signals.
Option 004 instruments (together with an external oscilloscope in XY mode), provide a
convenient method of identifying modulation formats such as 8 PSK, 16 QAM, and 64 QAM.
With typical receivers, the constellations \spin" due to the oset in frequency between the
receiver and the signal. This makes format identi cation very dicult. But, because of the
wide-bandwidth surveillance receiver's 1 Hz frequency tuning, this spinning movement can be
slowed to the point where it is almost stopped.

Switch between operating mode with the press of a button
Press 4USER5 and then RX_MODE for use as a wide-bandwidth surveillance receiver.
NNNNNNNNNNNNNNNNNNNNNNN
Press 4MENU5 for use as a spectrum analyzer.
This is the default state when the instrument is rst turned on.
Press 4DISPLAY5 to access functions for controlling the display.
You will seldom need to use this key. For information on functions accessed with this key,
refer to the HP 70004A DISPLAY Operating Manual .
Press 4INSTR5 to switch between multiple instrument windows.
Multiple instrument windows must rst be con gured as shown in Chapter 3.
vii
Changing measurement parameters is easy
Use the front-panel knob, step keys, or numeric keypad to enter new measurements settings.
For example, press the 4CENTER5 key to change the displayed center frequency. After changing
the setting, pressing the 4HOLD5 key disables the keypad, knob, and step keys until another
function is selected.
Use the 4 5 (backspace) key to speed your navigation through softkey menus. When pressed,
the previous softkey menu is displayed. Also, use this key to backspace over numbers entered
using the data-entry keypad.

Getting Started 1-1
To install the receiver
1. Inspect the shipping container or cushioning material for damage.
If there is damage or a defect, save the packing materials, le a claim with the carrier,
then contact the nearest Hewlett-Packard sales and service oce for immediate repair
or replacement.
2. Make sure the instrument's line-voltage selectors are set to the same voltage as the power
source.
CAUTION Before turning the instrument on, be sure the LINE VOLTAGE SELECTOR is set
to the correct voltage for the power source. Failure to do this may cause
damage (a blown fuse) to the system when the power cable is plugged in.
Note Option 400 instruments for 400 Hz operation come with an external in-line
isolation transformer for use with the HP 70001A mainframe. The isolation
transformer protects the user from shock hazard. The in-line isolation
transformer must be removed for 60 Hz power-source operation. Failure to
remove the in-line transformer may result in a blown fuse. The HP 70004A
display/mainframe does not require an option to operate on 400 Hz.
WARNING Do not operate a 400 Hz option receiver on a 400 Hz power line without the
attached in-line isolation transformer for the HP 70001A mainframe. Failure to
follow this precaution can result in personal injury.
