ab
a. This specification applies to the result labeled "(Pk-Pk)/2".
b. For optimum measurement, ensure that the channel bandwidth is set wide enough to capture the
significant RF energy. Setting the channel bandwidth too wide will result in measurement errors.
(Rate: 1 to 20 kHz
c
Deviation: 0.2 to 6 rad)
c. Rate is a modulation rate in Hz.
±(1 rad × (0.005 + (rate/1 MHz)))

PM Rate Accuracy
b
(Rate: 1 to 10 kHz)
±0.2 Hz (nominal)
Carrier Frequency Error
d
d. tfa = transmitter frequency
× frequency reference accuracy.
±0.02 Hz (nominal) + tfa
Assumes the signal is still visible
in the channel BW with offset.
Carrier Power Same as Absolute Amplitude
