ROUTe:MONitor:STATe
Syntax
ROUTe:MONitor:STATe <mode>
ROUTe:MONitor:STATe?
Description
This command disables or enables the Monitor mode. The Monitor mode is equivalent to making continuous measurements on a single channel with an infinite scan count. Only one channel can be monitored at a time but you can change the channel being monitored at any time. This feature is useful for troubleshooting your system before a test or for watching an important signal.
Used With:
34921A through 34925A Multiplexer Modules
34950A Digital I/O Module (digital input and counter channels only)
34952A Multifunction Module (digital input and totalizer channels only)

Remarks
Channels do not have to be part of an active scan list to be monitored; however, the channel must be configured for a measurement in order to be monitored (see CONFigure and SENSe commands).
The Monitor mode is automatically enabled on all channels that are part of the active scan list (see ROUTe:SCAN command).
A scan always has priority over the Monitor function (see ROUTe:SCAN command).
The Monitor mode ignores all trigger settings (see TRIGger:SOURce command) and takes continuous readings on the selected channel using the IMMediate (continuous) source.
Use the ROUTe:MONitor:MODE command to select whether the Monitor mode uses a module channel or the internal DMM.
Use the ROUTe:MONitor[:CHANnel] command to select which channel will be displayed on the front panel in the Monitor mode. Use the ROUTe:MONitor[:CHANnel]:ENABle command to enable monitor operations on the desired channels.
Any channel that can be "read" by the instrument can be monitored. This includes any combination of temperature, voltage, resistance, current, frequency, or period measurements on multiplexer channels. You can also monitor a digital input channel or the totalizer count on the digital modules.
Mx+B scaling and alarm limits are applied to the selected channel during a Monitor and all alarm data is stored in the alarm queue (which will be cleared if power fails).
For monitor operations using a multiplexer module, an error is generated if the internal DMM is disabled (see INSTrument:DMM[:STATe] command) or not installed in the mainframe. The internal DMM is not required for monitor operations on the digital modules.
The count on a totalizer channel is not reset when it is being monitored (the Monitor ignores the totalizer reset mode).
If a channel that is currently being monitored is manually closed (see ROUTe:CLOSe command) or opened (see ROUTe:OPEN command), the Monitor operation will be disabled on that channel.
Readings acquired during a Monitor are not stored in memory but they are displayed on the front panel; however, all readings from a scan in progress at the same time are stored in memory.
Return Format
The query command returns "0" (OFF) or "1" (ON).
Examples
The following program segment configures channel 3 in slot 1 for dc voltage measurements, enables monitoring on the channel, and turns on the Monitor mode.
CONF:VOLT:DC (@1003)
ROUT:MON:CHAN (@1003)
ROUT:MON:CHAN:ENAB ON,(@1003)
ROUT:MON:STAT ON
The following query returns the state of the Monitor mode.
