The Giga-tronics 8650A
Series Universal Power
Meters have the extensive
measurement capabilities and
unique features required to
test today’s sophisticated
communications systems
faster and more accurately.
TDMA
The 8650A can automatically
measure the average power
of pulse modulated signals or
pulse signals that are ampli-
tude modulated during the
pulse ‘on’ period — such as
TDMA signals.
Using the exclusive Burst
Average Power mode (BAP),
the average power reading in
the pulse burst is automati-
cally measured between the
3 dB points. Therefore, the
duty cycle can change in time
without affecting the accura-
cy of the meter reading. This
method eliminates the need
to manually set time gating,
which can add errors if the
gate is not set accurately.
