•
‘/nquery/’ indicates that this value can only be set, and not demanded. Do not send the
‘/nquery/’ string to the device, it is just written in this manual to explain the command.
For example you can’t request a trigger command.
•
All commands without ‘/qonly/’ and ‘/nquery/’ can be read and set.
•
<NRf> are float numbers
•
<NRi> are integer numbers
•
<list> stands for <(<NRf>:<NRf>)>. With this construct you can request several values
which are stored in an array, for example harmonic values. To get the 3
rd
to 11
th
harmonic
of the voltage of the second measuring channel you have to write in SHORT command set:
HUAM2? (3:11)
For the complete syntax rules please take a look at the Programmer’s Guide!
Examples showing the syntax
Equivalent SCPI commands for reading the TRMS value of the 1
st
measuring channel:
:FETCh:CURRent:TRMS?
:FETC:CURR:TRMS?
:FETC:CURR:TRMS1?
As SHORT command it would be
ITRMS? or ITRMS1?
Please note that there is no space before the ‘1’ and no space before the ‘?’!
Command for reading the harmonic voltages from the 2
nd
to the 4
th
harmonic (3 values):
:FETC:HARM:VOLT:AMPL? (2:4)
Please notice that there is at least one space between the question mark and the
parameters!
Command for setting the 250V range:
:SENS:VOLT:RANG 250
Please notice that there is at least one space before the parameter 250!
Command for setting the 250V range in the 3
rd
channel:
:SENS:VOLT:RANG3 250
Please notice that there is no space before the suffix and at least one space before the
250!
Commands for setting and reading a filter in group B (short language):
FILT 5,1
FILT? 1
For group A you can write:
FILT 5,0 or FILT 5
FILT? 0 or FILT?
For more examples please take a look at the Programmer’s Guide!
