Measuring Bluetooth - Agilent Technologies EPM-P Series Programming Manual

Measuring Bluetooth

The following procedure shows you how to measure the peak and average
power in a single Bluetooth DH1 data burst. Triggering is achieved using
the rising edge of the burst. The trigger is configured for a power level of
-20 dBm on a rising edge. A trigger hold off is also setup for 650 μs,
disabling the trigger until the current time slot is measured. The
measurement gate is configured to measure the peak and average power
in a 366 μs period, 0.2 μs after the trigger. The display is configured to
show the peak and average power in the lower window in numeric format,
while the upper window shows the power trace over 6 time slots starting
50 μs before the trigger.
Note The E9321A and E9325A sensors are best suited. The E9321A and
E9325A are not recommended due to lack of bandwidth.

Power Meter Remote Operation
Clears error queue
Resets meter settings to their
default states
The system error query
should return "0: No Error"
The sensor type query
should return one of the
following:
E9322A|E9323A|
E9326A|E9327A
The Bluetooth setup is only
valid with these sensors
Sets the measurement
frequency to 2400 MHz
Only send this command if
using an E9322A or E9326A
Sets gate1 start point to
200 ns after the trigger
Sets gate1 length to 366 μs
Puts meter in "wait for
trigger" state
Selects internal trigger
