Preparing Your Spectrum Analyzer for Use
Detailed information for all of the steps in this process is included in this chapter.
1. Unpack the spectrum analyzer and inspect it.
2. Verify that all of the accessories and documentation has been shipped.
3. Check that the line voltage selector is set to the proper voltage.
4. Check that the correct fuse is in place.
Warning
Failure to ground the spectrum analyzer properly can result in personal injury. Use an ac power outlet that has a protective earth contact.
DO
NOT defeat the earth grounding protection by using an extension cable,
power cable, or autotransformer without a protective ground conductor.
Caution
Do
not connect ac power until you have verified that the line voltage is correct,
the proper fuse is installed, and the line voltage selector switch is properly positioned, as described in the following paragraphs. Damage to the equipment could result.
5. Connect the power cable to the spectrum analyzer and turn it on.
Warning
Install the product so that the detachable power cord is readily
identifiable and easily reached by the operator. The detachable power cord is the product disconnecting devise. It disconnects the mains
circuits from the mains supply before other parts of the product. The front panel switch is only a standby switch and is not a LINE switch. Alternatively, an externally installed switch or circuit breaker (which is readily identifiable and is easily reached by the operator) may be used as a disconnecting device.
6. Execute the self-calibration routines.
1-2 Preparing For Use
Initial Inspection
Inspect the shipping container for damage. If the shipping container or cushioning material is damaged, keep it until you have verified that the contents are complete and you have tested the spectrum analyzer mechanically and electrically.
Table l-l contains the accessories shipped with the spectrum analyzer. If the contents are incomplete or if the spectrum analyzer does not pass the verification tests in the calibration
guide, notify the nearest Hewlett-Packard office. If the shipping container is damaged or the
cushioning material shows signs of stress, also notify the carrier. Keep the shipping materials for the carrier’s inspection. The HP office will arrange for repair or replacement without waiting for a claim settlement.
If the shipping materials are in good condition, retain them for possible future use. You may wish to ship the spectrum analyzer to another location or to return it to Hewlett-Packard for service. See “How to Return Your Analyzer for Service,”
in Chapter 9 for more information
about shipping materials.

1-4 Preparing For Use
Checking the Fuse
The recommended fuse is size 5 by 20 mm, rated
F5A,
250 V (IEC approved). This fuse may be
used with input line voltages of 115 V or 230 V. Its HP part number is 2110-0709.
With an input line voltage of 115 V an alternate fuse can be used. In areas where the recommended fuse is not available, a size 5 by 20 mm, rated fast blow, 5 A, 125 V (ULXSA approved) fuse may be substituted. Its HP part number is 2110-0756.
The line fuse is housed in a small container beside the rear-panel power connector. See Figure l-3. The container provides space for storing a spare fuse, as shown in the figure.
To check the fuse, insert the tip of a screwdriver in the slot at the middle of the container and pry gently to extend the container.
Warning
For continued protection against fire hazard replace line fuse only with
same type and rating
(5A/250V).
The use of other fuses or material is
prohibited.
Note
The fuse container is attached to the line module; it cannot be removed.
The fuse closest to the spectrum analyzer is the fuse in use. If the fuse is defective or missing, install a new fuse in the proper position and reinsert the fuse container.

Power Cable
The spectrum analyzer is equipped with a three-wire power cable, in accordance with international safety standards. When connected to an appropriate power line outlet, this cable grounds the instrument cabinet.
Warning
Failure to ground the spectrum analyzer properly can result in personal injury. Before turning on the spectrum analyzer, you must connect its protective earth terminals to the protective conductor of the main power cable. Insert the main power cable plug only into a socket outlet that has
a protective earth contact. DO NOT defeat the earth-grounding protection
by using an extension cable, power cable, or autotransformer without a protective ground conductor.
If you are using an autotransformer, make sure its common terminal is
connected to the protective earth contact of the power source outlet socket.
Various power cables are available to connect the spectrum analyzer to the types of ac power outlets unique to specific geographic areas. The cable appropriate for the area to which the spectrum analyzer is originally shipped is included with the unit. You can order additional ac power cables for use in different areas.

Preparing For Use
l-7
Turning on the Analyzer for the First Time
When you turn the spectrum analyzer on for the first time, you should perform frequency and amplitude self-calibration routines to generate correction factors and indicate that the unit is functioning correctly. The spectrum analyzer should be allowed to warm-up for 30 minutes before performing the self-calibration routines. See “When Is Self-Calibration Needed?” in Chapter 2 for helpful guidelines on how often the self-calibration routines should be performed.
Perform the following steps:
1. Fbr an HP 85901, HP
8592L,
HP 8591 E, HP 85933, HP
8594E,
HP
8594L,
HP
8595E,
or
HP 85963 ensure the reference connector is connected between the 10 MHz OUTPUT and
EXT REF IN rear-panel connectors. See Figure l-4.
REFEPENCE
Figure 1-4. Reference Connector
If you wish to use an external 10 MHz source as the reference frequency, disconnect the reference connector from the rear-panel and connect an external reference source to the EXT REF IN connector on the rear panel.
2. Plug the power cord into the spectrum analyzer.
3.
Press (LINE).
After a few seconds, the screen displays the firmware revision date in the YYMMDD format. For example, 930522 indicates May 22, 1993. This is a change from previous revisions where any firmware date used the DDMMYY format prior to 930506.
Note
Record the firmware date and keep it for reference. If you should ever need to call Hewlett-Packard for service or with any questions regarding your spectrum analyzer, it will be helpful to have the firmware date readily available.
If your spectrum analyzer is equipped with Option 021 (HP-IB interface), the appropriate interface address (HP-IB ADRS : XX) also appears on the screen.
If your spectrum analyzer is equipped with Option 023 (RS-232 interface), the baud rate (RS232 : XXXX) is displayed.
4. To meet spectrum analyzer specifications, allow a 30 minute warm-up before attempting to
make any calibrated measurements. Be sure to calibrate the spectrum analyzer only afler the spectrum analyzer has met the operating temperature conditions.
5. Connect the type N (m) to BNC (f) connector (shipped with the spectrum analyzer) to the INPUT
5OQ.
Connect the 500 coaxial cable (also shipped with the instrument) between the
front-panel CAL OUT and the INPUT 500 connector. If the spectrum analyzer has Option
1-8 Preparing For Use
001
(7562
input), use the 750 calibration cable shipped with the analyzer. Use only 750
connectors to avoid damage to the RF input connector.
Note
Option 105 only: Remove all connections to the GATE TRIGGER INPUT
rear-panel connector before performing the self-calibration routines.
6. Perform the frequency and amplitude self-calibration routine by pressing (CAL) and CAL FREQ & AMPTD . During the frequency routine, CAL: SWEEP, CAL: FREQ, and CAL: SPAN
are displayed as the sequence progresses. For an Option 102, CAL: FM GAIN + OFFSET is also displayed.
During the amplitude routine, CAL; AMPTD, CAL: 3 dB BW, CAL:
ATTEN,
and CAL:
LOGAMP
are
displayed as the sequence progresses. CAL: DONE appears when the routine is completed.
Any failures or discrepancies produce a message on the screen; see Chapter 9.
7. When the frequency and amplitude self-calibration routines have been completed successfully, store the correction factors by pressing CAL STORE.
The self-calibration routines calibrate the spectrum analyzer by generating correction factors. The
softkey
CAL STORE stores the correction factors in the area of spectrum analyzer
memory that is saved when the spectrum analyzer is turned
off;
the spectrum analyzer will
automatically apply these factors in future measurements. If CAL STORE is not pressed, the correction factors remain in effect until the spectrum analyzer is turned off.
Performing the Tracking-Generator Self-Calibration Routine
For spectrum analyzers with Option 010 or 011, the tracking-generator self-calibration routine should be performed prior to using the tracking generator.
Note
Since the tracking generator calibration routine depends on the accuracy of the absolute amplitude level of the spectrum analyzer, the spectrum analyzer
amplitude calibration should be done prior to using CAL TRK GEM .
1. To calibrate the tracking generator, connect the tracking generator output (RF OUT
5OR)
to the spectrum analyzer INPUT 500 connector, using an appropriate cable and BNC-to-Type N adapters. If the spectrum analyzer has Option 001 (750 input), use the
75Q
calibration
cable shipped with the analyzer. Use only
75fl
connectors to avoid damage to the RF input
connector.
Note
A low-loss cable should be used for accurate calibration. Use the
509
cable shipped with the spectrum analyzer. If the analyzer has Option 001 (75n input), use the

Performing the YTF Self-Calibration Routine
For preselected spectrum analyzers (HP
8592L,
HP 85933, HP
8595E,
and HP 85963) only, the yig-tuned filter (YTF) self-calibration routine should be performed periodically. See “When Is Self-Calibration Needed?” in Chapter 2 for helpful guidelines on how often the self-calibration routines should be performed.
To perform the YTF self-calibration routine, use the following procedure:
1. Connect a low-loss cable (such as HP part number 8120-5148) from 100 MHz COMB OUT to the spectrum analyzer input. For the HP 85953, use the CAL OUT, instead of the COMB
OUT, as the spectrum analyzer input.
2. Press (CAL) then CAL YTF . The YTF self-calibration routine completes in approximately:
Model Number YTF Cal Time
HP 8592L
7 minutes
HP 85933
7
minutes
HP
85953
3
minutes
HP
85963

minutes
3. Press (CAL) then CAL STORE
_
When the self-calibration routines have been completed successfully, the spectrum analyzer is
ready for normal operation.

Preparing For Use
Electrostatic Discharge
Electrostatic discharge (ESD) can damage or destroy electronic components. All work on electronic assemblies should be performed at a static-safe work station. Figure l-5 shows an example of a static-safe work station using two types of ESD protection:
H
Conductive table-mat and wrist-strap combination.
n Conductive floor-mat and heel-strap combination.
Both types, when used together, provide a significant level of ESD protection. Of the two, only
the table-mat and wrist-strap combination provides adequate ESD protection when used alone.
To ensure user safety, the static-safe accessories must provide at least 1 MR of isolation from ground. Refer to
‘fable
l-4 for information on ordering static-safe accessories.
Warning
These techniques for a static-safe work station should not be used when working on circuitry with a voltage potential greater than 500 volts.

Reducing Damage Caused by ESD
The following suggestions may help reduce ESD damage that occurs during testing and servicing operations.
n Before connecting any coaxial cable to an spectrum analyzer connector for the first time each
day, momentarily ground the center and outer conductors of the cable.
w
Personnel should be grounded with a resistor-isolated wrist strap before touching the center
pin of any connector and before removing any assembly from the unit.
n Be sure that all instruments are properly earth-grounded to prevent a buildup of static
charge.
