Performance Verification
3. Select Tools > A
lignments and select Align Now.
4. Set the RSA5100B:
Center
Setup > Settings > Freq & Span > Span
200 MHz
Span
Setup > Settings > Freq & Span > Span
300 kHz
5. Set the RF generator output frequency to 200 MHz. This is the reference
frequency.
6. Select the Peak key on the Markers control bar to set the Reference marker
(MR) to the carrier peak.
7. Adjust the signal generator output level to –4 dBm and turn RF On.
8. Record the Power Meter reading and the RSA5100B marker reading in the
IF Flatness table. (See Table 79.).
9. Set the RF generator output frequency to the next frequency in the IF Flatness
table that follows.
10. Leave the RSA5100B center frequency at 200 MHz and press the Peak key
on the Markers control bar.
11. Record the Power Meter reading and the RSA5100B marker reading in the
IF Flatness table.
12. Calculate the Δ Power Meter number: subtract the Power Meter reading at
200 MHz from the Power Meter reading at this frequency.
13. Calculate the Δ RTSA number: subtract the RSA5100B marker reading at
200 MHz from the RSA5100B marker reading at this frequency.
14. Calculate the IF Flatness Error using the formula:
R
F Flatness Error = Δ RTSA at this freq - Δ Power Meter at this freq
Readings are in dBm, error is in dB.
15. Repeat parts 9 through 14 for each of the remaining generator frequencies
shown in the Span = 300 kHz portion of the following table.
16. Record the highest Calculated IF Flatness Error for the Span setting into the
test record. (Limits are shown in the test record.)
17. Repeat steps 4 through 16 for Span settings of 20 MHz and 25 MHz, using the
appropriate span segment of the following table.
18. (Option B85/B16x only.) Repeat steps 4 through 16 for a 85 or 160 MHz
Span setting.
