error + frequency drift error + noise error ± 1 digit.

11. The 8902A fundamental Tuned RF Level measurement units are volts. Further
internal processing is done on this number to display all other units.
12. Tuned RF Level accuracy will be affected by residual FM of the source-under-test.
If the residual FM
peak
is >50 Hz measured over a 30 second period in a 3 kHz BW.
Tuned RF Level measurements should be made using the IF average detector (30
kHz BW) by using Special Function 4.4. The Tuned RF Level measurement sensi-
tivity when using the IF average detector is –100 dBm.
