:PWINdow <n>
[:SENSe[1]]:VOLTage:AC:DETector:PWINdow <n> Set peak detection window for ACV
<n> = 0.1 to 9.9 Peak spike detection window (in seconds)
DEFault 0.1sec window
MINimum 0.1sec window
MAXimum 9.9sec window
:PWINdow? Query spike detection window
:PWINdow? DEFault Query *RST default window
:PWINdow? MINimum Query lowest allowable window
:PWINdow? MAXimum Query largest allowable window
This command is used to set the detection window for peak spike measurements (:NPEak or
:PPEak). The instrument measures and displays the largest peak spike that occurs within each
specified detection window. For example, for a ½ second window, the instrument displays the
peak spike after every ½ second. See paragraph 2.4.1 (AC-TYPE; Positive Peak and Negative
Peak) for more information.
PRINT #1, "output 16; :volt:ac:det:pwin 1; pwin?" ' Specify 1 sec window
PRINT #1, "enter 16" ' Get response from 2002
:METHod <name>
[:SENSe[1]]:CURRent:DC:METHod <name> Specify measurement technique for DCI.
<name> = NORMal Normal DCI measurement technique
ICIRcuit In-circuit DCI measurement technique
:METHod? Query measurement technique
This command is used to select the DCI measurement technique. NORMal is used to make con-
ventional current measurements which are performed by breaking the circuit and placing the
ammeter in series with it.
The ICIRcuit selection allows you make an in-circuit current measurement of a wire or circuit
board trace. This measurement technique is performed by making four-wire INPUT connections
to the wire or trace (the AMPS input is not used). The instrument automatically performs a four-
wire ohms offset compensated measurement and calculates the current. See paragraph 2.4.2
(IN-CIRCUIT) for details.
PRINT #1, "output 16; :curr:dc:meth icir; meth?" ' Select in-circuit I
measure
PRINT #1, "enter 16" ' Get response from 2002
:SOURce <name>
[:SENSe[1]]:FREQuency:SOURce <name> Specify input source for FREQ.
<name> = CURRent Select current frequency input source
VOLTage Select voltage frequency input source
:SOURce? Query frequency input source
