a.
FUNCtion <name> [, <clist>]
Note that the <name> parameters in the table are enclosed in single quotes
(' '). However, double quotes (" ") can instead be used. For example:
FUNC 'VOLT:AC' = FUNC "VOLT:AC"
Scan configuration — When using the <clist> command to configure a 7702
scan channel, the scan channel must first be set to the appropriate function
before sending other commands to configure it. For example, to set scan chan-
nel 101 to use offset-compensated ohms, the following command sequence
would be sent:
FUNC 'FRES', (@101)
FRES:OCOM
ON, (@101)
If scan channel 101 was not first set for the Ω4 function, error +700 (Invalid
function in chanlist) will occur when trying to enable offset-compensated
ohms for that channel. Details on scanning are provided in
b.
FRESistance:OCOMpensated <b> [, <clist>]
The instrument does not have to be on the Ω4 function to enable offset-
compensated ohms. When Ω4 is selected, offset-compensated ohms will be
enabled.
When using the <clist> parameter to configure a 7702 scan channel for offset-
compensated ohms, that channel must already be set for Ω4. If set for another
function, a settings conflict (-221) will occur.
c.
TEMPerature:FRTD:RZERo <NRf> [, <clist>]
TEMPerature:FRTD:TYPE
TEMPerature:FRTD:ALPHa <NRf> [, <clist>]
TEMPerature:FRTD:BETA <NRf> [, <clist>]
TEMPerature:FRTD:DELTa <NRf> [, <clist>]
These commands are used to set the parameters for the USER RTD type. Note
that the RZERo command sets the "Ω at 0°C" parameter. When any of these
commands are sent, the USER RTD type is automatically selected.
d.
FREQuency:THReshold:VOLTage:RANGe <n> [, <clist>]
PERiod:THReshold:VOLTage:RANGe <n> [, <clist>]
These commands are used to specify the expected input level. The instrument
will then automatically select the most sensitive current or voltage threshold
range.
' Set scan channel 101 to Ω4 function.
' Enable offset-compensated ohms for
scan channel 101.
