Monitor Feature, Stored State Feature | Agilent Technologies 34980A

Monitor Feature

The 34980A monitor feature allows you to monitor readings acquired by the switch/measure system. You can also monitor readings acquired with the 34980A internal DMM. To monitor a measurement from the front panel, simply select the channel and press either the Measure [DMM] or [Channel] button to see a continually updated channel output or state on the front display. For programs, use the ROUTe:MONitor:DATA? Command. The command reads the data from the channel currently selected by the Monitor function. One reading is displayed for each monitor command. The Web interface can also be used to monitor a channel measurement.

The 3499A/B/C monitor feature allows users to continuously monitor a selected switch or module status from the front display. A channel monitor can be set up using the front panel buttons or instrument commands. The 3499A/B/C monitor output can be a specific switching channel, a digital I/O port or the state of all switches or digital I/O on one plug-in module. The 3499A/B/C allows a single channel to be monitored continuously even during an instrument scan.

Stored State Feature

The 34980A is also able to store/recall up to six (0 through

5)instrument setups. A stored setup state can be automatically recalled at any time, even during a power up state. The stored state feature contains the state of the plug-in modules including channel configurations, scanning setups, alarm values, and Mx + B scaling values. Location 0 is typically used for the Factory Reset and power down state, but can also be programmed with a new setup.

The 3499A/B/C is able to store and recall up to 50 instrument setup states with revision 4.0.

The instrument setups include the status of relay channels, and/or the static digital I/O state, module configuration, and scanning setups (scan lists, arm count, arm source, etc.). The 3499A/B/C is not able to automatically power up in a stored state.
