Channel Setup; Buffer; Scanning Commands - Keithley 2750 User Manual

Model 2750 Multimeter/Switch System User's Manual

Channel setup

The <clist> parameter is used to set up scan channels. For example, the following exam-
ples show how to set up scan channel 101:
FUNC 'VOLT', (@101)
VOLT:RANG 10, (@101)
VOLT:DIG 4.5, (@101)
VOLT:NPLC 3, (@101)
NOTE

Buffer

For front panel scanning, the reading count specifies the number of readings to store in the
buffer. For remote scanning, the sample count specifies the number of readings to store in
the buffer.
Readings stored in the buffer by the TRAC command (or by front panel data store opera-
tion) must be cleared before sending INITiate or READ? to take the instrument out of idle.
The following command clears the buffer:
TRACe:CLEar

Scanning commands

Scanning commands are listed in
follow the table.
NOTE
In the above command sequence, channel 101 is first set for DCV before sending
the other commands to set range, digits and rate. If channel 101 was instead set
to a different function (i.e., RESistance), the VOLT commands to set range, dig-
its and rate would generate error +700 (Invalid function in scanlist).
Query commands and optional command words are not included in
The unabridged SCPI tables are provided in
' Set 101 for DCV.
' Set 101 for 10V range.
' Set 101 for 4H digit resolution.
' Set 101 rate for 3 PLC.
' Clear buffer.
