Model 2750 Multimeter/Switch System User’s Manual Scanning 7-27
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) ' Set 101 for DCV.
VOLT:RANG 10, (@101) ' Set 101 for 10V range.
VOLT:DIG 4.5, (@101) ' Set 101 for 4H digit resolution.
VOLT:NPLC 3, (@101) ' Set 101 rate for 3 PLC.
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).
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 ' Clear buffer.
Scanning commands
Scanning commands are listed in Table 7-1. Additional information on these commands
follow the table.
NOTE Query commands and optional command words are not included in Table 7-1.
The unabridged SCPI tables are provided in Section 15.
