Performance Verification
Absolute Accuracy at
Calibration Point, LF path,
Preamp O N (only for
RSA5103B and RSA5106B)
1. Connect the RF g
enerator, power splitter, power meter, and RSA5100B.
(See Figure 11.)
2. Reset the RSA5100B to factory defaults: select Setup > Preset (Main).
3. Select Tools > Alignments and select Align Now.
4. Set the RSA5100B:
Reference Level - 10 dBm
Setup > Amplitude > Internal Settings > Ref Level
Center Frequency 100 MHz
Setup > Settings > Center
Internal Attenuator 10 dB (Auto unchecked)
Setup > Amplitude > Internal Attenuator
Internal Preamp Internal Preamp box checked
Setup > Amplitude > Internal Attenuator
LF Path
Setup > Acquire > Input Params
Use Low Freq signal path checked.
5. Set the RF Generator:
Output Frequency 10 MHz
Output Level –4 dBm
RF On
6. Set the frequency span (Span key) to 300 kHz.
7. Select the Peak key on the Markers control bar to set the Reference Marker
(MR) to the carrier peak.
8. Record the reading on the Power Meter and on the RSA5100B marker
amplitude.
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
RSA5100B Series Technical Reference 111
