ROUTe:MONitor:STATe
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:
- 34901A 20 Channel Multiplexer (2/4-wire) Module
- 34902A 16 Channel Multiplexer (2/4-wire) Module
- 34907A Multifunction Module (digital input and totalizer)
- 34908A 40 Channel Single-Ended Multiplexer Module
Parameters
Name Type Range of Values Default Value <mode> Boolean {OFF|0|ON|1} This is a required parameter.
Remarks
- Channels must be configured for a measurement in order to be monitored (see CONFigure and SENSe commands). Configuring a channel for a measurement makes it monitorable and makes it part of the scan list.
- 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.
- 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, no measurements are taken if the internal DMM is disabled (see INSTrument:DMM 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).
- 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 returns 0 (OFF) or 1 (ON).
Examples
The following program segment configures channel 3 in slot 100 for DC voltage measurements, enables monitoring on the channel, and turns on the Monitor mode.
CONF:VOLT:DC (@103)
ROUT:MON:CHAN (@103)
ROUT:MON:STAT ON
The following query returns the state of the Monitor mode.
