Bandwidth commands

3 to 3e5

Channel list parameter:
<clist> = (@SCH)
where: S = Mainframe slot number (1 or 2)
CH = Switching module channel number (must be 2 digits)
Examples: (@101) = Slot 1, Channel 1
(@101, 203) = Slot 1, Channel 1 and Slot 2, Channel 3
(@101:110) = Slot 1, Channels 1 through 10
Notes:
1. The <clist> parameter is used to configure one or more channels for a scan. Each channel in the <clist> must be set to the function
specified by the command. If not, a conflict error (-221) will occur. For example, RESistance:NPLCycles 1, (@101) is only valid if
scan channel 101 is set for the
Ω2 function.
2. For 60Hz line power, x = 60. For 50Hz line power, x = 50.
3. For 60Hz line power, x = 1.67e-4. For 50Hz line power, x = 2e-4.
4. For 60Hz line power, the default is 16.67msec. For 50Hz line power, the default is 20msec.
5. Commands to set rate for ACV and ACI are only valid if bandwidth is set to 300 (300Hz to 300kHz). See “Rate and bandwidth
conflict error,” page 4-12, for details.
6. The instrument will actually accept a parameter value up to 10e6, but it will default to 3e5.
7. [:DC] is optional for the commands to set DCV and DCI integration rate.
