Transmit power measurement
The transmit power measurement determines the average
power for an RF signal burst at or above a user specified
threshold value. The threshold value may be absolute, or
relative to the peak value of the signal.

Power versus time measurement
Power versus time measures the average power during the
“useful part” of the GSM burst and verifies that the power
ramp is within the GSM mask. The specified GSM masks
for both base transceiver stations and mobile stations are
provided. Power versus time also lets you view the rise, fall,
and “useful part” of the burst. The timings are referenced
to the transmitter from bit 13 to 14 of the training sequence
(midamble).

Phase and frequency error measurement
Phase and frequency error measures the modulation quality
of a GSM transmitter. Phase and frequency error can be
displayed both numerically and or graphically. A binary representation of the demodulated data bits is also available.

Output RF spectrum measurement
The output RF spectrum measurements determine the
spectral energy emitted into the adjacent channels. The
measurements are divided into two types spectrum due to
0.3 GMSK modulation and noise, and spectrum due to
switching transients (burst ramping). A single offset can be
examined with a corresponding trace or up to 15 offsets
can be measured with a tabular data display
