Rel commands for
TEMP
2
[SENSe[1]] Optional root command.
:TEMPerature:REFerence <n> [, <clist>] Specify rel value; <n> = -328 to 3310 (°C). 0
:TEMPerature:REFerence:STATe <b>
[, <clist>]
Enable/disable rel; <b> = ON or OFF. OFF
:TEMPerature:REFerence:ACQuire [, <clist>] Use input signal as rel value.
Rel commands for FREQ
[SENSe[1]] Optional root command.
:FREQuency:REFerence <n> [, <clist>] Specify rel value; <n> = 0 to 1.5e7 (Hz). 0
:FREQuency:REFerence:STATe <b> [, <clist>] Enable/disable rel; <b> = ON or OFF. OFF
:FREQuency:REFerence:ACQuire [, <clist>] Use input signal as rel value.
Rel commands for PERIOD
[SENSe[1]] Optional root command.
:PERiod:REFerence <n> [, <clist>] Specify rel value; <n> = 0 to 1 (sec). 0
:PERiod:REFerence:STATe <b> [, <clist>] Enable/disable rel; <b> = ON or OFF. OFF
:PERiod:REFerence:ACQuire [, <clist>] Use input signal as rel value.
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
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 rel (reference) command. If not, a conflict error (-221) will occur. For example, VOLTage:AC:REFerence 1,
(@101) is only valid if scan channel 101 is set for the ACV function.
2. [:DC] is optional for the commands to set DCV and DCI rel.
