Veriﬁcation Procedures

2-6 Calibration Guide

Conﬁgure the Signal Generator

1. Press Frequency. Enter 277 using the numeric keypad and press the kHz terminator

softkey.

2. Press Amplitude. Enter −15 using the numeric keypad and press the dBm terminator

softkey.

Conﬁgure the Spectrum Analyzer

1. Preset the spectrum analyzer.

2. Set the analyzer to external 10 MHz reference.

3. Set the center frequency to 277 kHz.

4. Set the frequency span to 100 Hz. (This will result ina1Hzresolution bandwidth with

a digital ﬁlter.)

Measure the Power Level Accuracy

1. Connect the signal generator’s RF OUTPUT through the 6 dB attenuator to the

spectrum analyzer’s RF input.

2. Transfer the power level results for each frequency at −15 dBm from the Measured

Power column in Table 2-2 or Table 2-3 as appropriate, to the Power Meter Reading for

−15 dBm column in Table 2-4, “Power Level Accuracy Setup 2 (All Signal Generators),”

on page 2-15.

3. On the spectrum analyzer, select

Marker Normal Mode and then select the Peak Search

function. This activates the marker and sets it to the signal peak.

4. On the spectrum analyzer, ensure that the marker is at the signal peak and use the

MKR-> menu to set the marker to the reference level. If necessary, select Peak Search to

ensure that the marker is at the signal peak.

5. With the marker at signal peak, select the Marker Delta function. This will set the marker

to measure relative amplitude from a reference of 0 dB. If the marker does not read

0 dB, press

Marker Normal > Peak Search > Marker Delta until the marker reads 0 dB.

6. Decrease the signal generator amplitude in 10 dB steps as shown in Table 2-4. At each

10 dB step, select Peak Search to ensure that the marker is at the signal peak.

7. Measure the power levels shown in the Power Level Setting (dBm) column of Table 2-4

for the current frequency, and record the values in the Spectrum Analyzer Marker (dB)

column.

8. Return the spectrum analyzer reference level and the signal generator amplitude to

−15 dBm. Set the signal generator frequency and the spectrum analyzer’s center

frequency to the next frequency listed in Table 2-4 and repeat the process from step 3.

Continue until all of the frequencies have been measured and recorded (to the

maximum frequency of your signal generator).
