Advanced Source and Measurement Functions 6
Model N6705 User’s Guide 165
One way of dealing with AC line ripple is to use a Hanning window.
The Hanning window applies a cos
4
weighting function to the data
when calculating average measurements. This attenuates the AC
noise in the measurement window. The best attenuation is achieved
when at least three or more waveform cycles are in the measurement.
To select the Hanning window function, use:
SENS:WIND HANN,(@1)
Select the Measurement Trigger Source
NOTE
An immediate trigger command over the bus will generate an immediate trigger
regardless of the trigger source.
Unless you are using a TRIG:ACQ command to trigger the
measurement, select a trigger source from the following:
BUS
Selects GPIB device trigger, *TRG, or <GET> (Group Execute Trigger).
CURRent<1-4>
VOLTage<1-4>
Triggers the measurement when the current or voltage of the corresponding
output passes through the specified level.
EXTernal
Selects the trigger input BNC connector. Requires a low-true trigger signal.
PIN<n> Selects a pin on the digital port. <n> specifies the pin number. The pin must be
configured as a Trigger Input to be used as a trigger source (see Appendix C).
TRANsient<1-4> Selects the output channel’s transient system as the trigger source.
<n> specifies the channel.
The following commands select a trigger source. To select Bus
triggers for output 1:
TRIG:ACQ:SOUR BUS,(@1)
To select Digital pin triggers on pin 3 for output 1:
TRIG:ACQ:SOUR PIN3,(@1)
To select transient output triggers from output 3 for output 1:
(Output 3 will generate the trigger signal for output 1)
TRIG:ACQ:SOUR TRAN3,(@1)
To enable trigger signals for output Steps or Lists: (Specify if the list
trigger occurs at the Beginning Of the Step, or End Of the STep.)
STEP:TOUT ON,(@3)
LIST:TOUT:BOST 1, (@3)
LIST:TOUT:EOST 1, (@3)
To select a voltage or current level of another output as the trigger
for output 1: (Output 3 will generate the voltage or current level to
trigger output 1.)
TRIG:ACQ:SOUR VOLT3,(@1)
TRIG:ACQ:SOUR CURR3,(@1)
