Performance Verification
Absolute Accuracy at
Calibration Point, RF Path,
Preamp ON
1. Connect the RF g
enerator, power splitter, power meter, and RSA5100B.
(See Figure 11.)
2. Reset the RSA5
100B to factory defaults: select Setup > Preset (Main).
3. Select Tools > Alignments and select Align Now.
4. Set the RSA5100B:
Reference Level - 30 dBm
Setup > Amplitude > Internal Settings > Ref Level
Center Frequency 100 MHz
Setup > Settings > Center
Internal Attenuator 10 dB (Auto unchecked)
Setup >
Amplitude > Internal Attenuator
Inter
nal Preamp Internal Preamp box checked
Setup > Amplitude > Internal Attenuator
5. Set the RF Generator:
Output Frequency 100 MHz
Output Level –24 dBm
RF On
6. Se
t the frequency span (Span key) to 300 kHz.
7. Select the Peak key on the Markers control bar to set the Reference Marker
(M
R) to the carrier peak.
8. Record the reading on the Power Meter and on the RSA5100B marker
a
mplitude.
9. Calculate the Absolute Amplitude Accuracy:
Delta = RSA5100B reading - Power Meter reading
Readings are in dBm, error is in dB.
10. Record the Absolute Amplitude Error in the test record. (Limits are shown in
the test record.)
11. Repeat steps 6 through 10 for frequency spans of 1 MHz and 41 MHz (Option
B40, B85, and B16x).
