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 in a 1 Hz resolution 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).
