The instructions in this document are for use by qualified personnel

only.Toavoid electrical shock, do not perform any servicing unless

you are qualified to do so.

The opening of covers or removal of parts is likely to expose

dangerous voltages. Disconnect the instrument from all voltage

sources while it is being opened.

The power cord is connected to internal capacitors that may remain

live for five seconds after disconnecting the plug from its power

supply.

This is a Safety Class 1 Product (provided with a protective earthing

When to Calibrate Your Receiver

Note

To meet specied absolute amplitude accuracy,your receiver must

be calibrated. For accurate calibration, ambient temperature must

be 20 to 30 degrees centigrade. Your receiver must be stabilized at

room temperature for at least two hours, to allow comb amplitude

to stabilize.

Calibrating Receiver INPUT 1 and INPUT 2

Note

Receiver INPUT 1 and receiver INPUT 2 are input 1 and input 2

on the HP 85685A RF preselector.

When calibrating receiver INPUT 1 and receiver INPUT 2,

complete the pro cedure for each new combination of frequency

range, resolution bandwidth, logarithmic/linear scale, and

attenuation settings.

To calibrate receiver INPUT 1 and receiver INPUT 2:

1. Connect the 100 MHz CAL OUTPUT on the spectrum analyzer

to receiver INPUT 2 on the RF preselector.

2. On the quasi-peak adapter, select the bypass path by pressing

the BYPASS key in the INSTR FUNCTION group. The LED

Preselector Peaking for Receiver INPUT 3

To obtain the specied absolute amplitude accuracy for the 2 GHz

to 22 GHz frequency bands, the tracking preselector must be

peaked for each signal. If this is not done, displayed signals above

2 GHz are likely to be displayed as much as 5 dB to 7 dB lower.

This discrepancy could cause amplitude errors of00.7 to01dB,

which becomes signicantgiven the62 dB amplitude accuracy

specication.

To determine the true amplitude of a signal, place the marker on the

peak of the signal and press

automatically ne tunes its preselector lter, using a digital-to-analog

converter (DAC), for maximum signal amplitude, so the signal is not

attenuated by the lter skirts.

Use the factory-default preselector DAC setting of 32 (obtained by

Correcting Receiver INPUT 3 Using a Calibration Table

To obtain sp ecied absolute amplitude accuracy for signals

measured through receiver INPUT 3, apply the frequency-dep endent

correction factors to signal amplitude measurements. Because of the

preamplier gain, signals will be displayed on the receiver displayat

an amplitude higher than the actual signal amplitude.

Figure 1-1 is a sample calibration table. The calibration data corrects

for preamplier gain, preamplier frequency response, and spectrum

analyzer frequency resp onse for both 0 dB and 10 dB spectrum

analyzer attenuation after the receiver calibration routine has been

completed. Calibration factors are provided every 50 MHz from

1.0 GHz to 22 GHz for each frequency band.

Calibration data is provided in two forms in the calibration table:

gain in dB, and correction factor with a specic reference level oset.

Description

Calibration INPUT 1". The settings used during each of these two

calibration routines are shown in the tables on the following pages.

Receiver Calibration INPUT 1 consists of two setups. The rst setup

calibrates the spectrum analyzer with the RF preselector in bypass

mode. Recall-9 calibrates the sp ectrum analyzer's center frequency

for narrow resolution bandwidths of 10 Hz through 1 kHz.

In the second setup, receiver INPUT 1 is calibrated at predetermined

points for amplitude accuracy using the comb generator output.

These points are chosen bytheinternal calibration sequence (CAL

SEQ) in the RF preselector. receiver INPUT 1 is calibrated between

9 kHz and 50 MHz.

Tomake calibrated measurements with the EMI receiver system,

CAL SEQ must be run for each set of EMI receiver system settings.

EMI receiver system.

This test measures the bandwidth accuracy of the

Description

and 60 dB bandwidth of the 10 Hz to 3 MHz resolution bandwidths

in the receivers. The 6 dB bandwidth accuracy is specied only for

the 10 Hz to 300 Hz resolution bandwidths. The impulse bandwidth

is specied for the wider resolution bandwidths. However, the

selectivity is specied for all bandwidths, so the 6 dB bandwidth is

measured for all bandwidths.

Resolution bandwidth settings of 10 Hz,30Hz,100Hz, and 300 Hz

are sp ecied as 6 dB bandwidths and are tested separately.

In the rst setup, the 1 kHz to 3 MHz impulse bandwidths are

measured in the EMI receiver system. The receiver's amplitude

response to the same pulsed-RF signal is measured both in pulse

mode and in line mo de. Amplitude dierence and pulse repetition

frequency are measured by a frequency counter. A synthesizer is used

to correct IF gain, log delity, and bandwidth switching errors in the

Purpose

pulsed RF input signal relative to that of a CW input signal and the

system response as a function of pulse repetition frequency, according

to CISPR* requirements.

This test measures the EMI receiver system's response to a

Description

signal rather than a video pulse, because the necessary equipment

is readily available, easily calibrated, and exible to use. Pulsed

RF setup considerations and the relationship between the two

techniques are explained in HP Application Note 150-2, and in

CISPR Publication 16, Appendix Q.

The output of the HP 3335A synthesizer/level generator is

modulated by the pulse generator using the pulse mo dulator to

yield a pulsed RF signal. The system is tested, through eachof the

three 6 dB bandwidth lters of the HP 85650A quasi-peak adapter,

with a pulse repetition frequency (PRF) corresponding to CISPR

specications.

Isolation Check

The p ower sensor is disconnected, the 3 dB

attenuator is connected to the input of the unit

under test, and the HP 85650A quasi-peak adapter

is put into bypass mode. The input signal is

measured with the EMI receiver system. The

pulse generator is set to dc bias the modulator in

its OFF state and the signal is measured again.

The two readings are compared, to verify that

the mo dulator's isolation is greater than 70 dBc.

This ensures accuracy of the pulsed RF sp ectral

intensityin low pulse repetition frequencies by

limiting the carrier source feedthrough component.

Description

rst setup calibrates the spectrum analyzer with the RF preselector

in bypass mode. Recall-9 calibrates the spectrum analyzer's center

frequency for narrow resolution bandwidths of 10 Hz through 1 kHz.

In the second setup, receiver INPUT 2 is calibrated at predetermined

points for amplitude accuracy using the comb generator output.

These points are chosen bytheinternal calibration sequence (CAL

SEQ) in the RF preselector. receiver INPUT 2 is calibrated between

20 MHz and 2 GHz.

Tomake calibrated measurements with the EMI receiver system,

CAL SEQ must be run for each set of EMI receiver system settings.

This test runs CAL SEQ at the settings that will be used in

subsequent tests. The resulting calibration factors are stored in the

controller memory and loaded into the RF preselector when they are

needed.

\Calibration INPUT 2" consists of two setups. The
