General Safety Considerations

WARNING

ARNING

W

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

ground incorporated in the power cord). The mains plug shall only

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.
