17 Poll the status of the power meter by sending *ESR?. *ESR? will return
a 1 when buffering is completed. Use FETCh? to retrieve all the
buffered measurement.
Determine the Right Step to be Set
Number of frequency step can be calculated by using equation below:
Step = (f
stop
– f
start
+ Interval)/Interval
where,
Step = Number of frequency step
f
start
= Frequency sweep’s start point
f
stop
= Frequency sweep’s stop point
Interval = Frequency step size
Example
When f
start
= 1 GHz and f
stop
= 5 GHz with given interval of 0.5 GHz, the
Step
should be set to
Step
= (f
stop
– f
start
+ Interval)/Interval
= (5 GHz – 1 GHz + 0.5 GHz)/0.5 GHz
= 9
NOTE
In both power sweep and frequency sweep mode, the meter TRIG OUT to power source
TRIG IN connection is optional. You may choose to setup the Dwell time in the power
source step setting to cater the maximum settling time required by the power meter.
