Disconnect from CMW500

Get CMW500 identification (*IDN?): manufacturer, model, serial, firmware

Get CMW500 connection and configuration status

Query installed hardware and software options

Drain the instrument's SCPI error queue and report what it rejected. A write command returns no response, so this is the only way to learn that a setting silently failed to apply. Reading the queue clears it.

Report which technology families this instrument can actually be asked to use, based on its installed options. Call this before planning a campaign: a CMW500 is a chassis, and WLAN, Bluetooth, LTE measurement and LTE signaling are each separately licensed. Without it, an unlicensed application answers '-113 Undefined header', which reads like a client bug rather than a missing licence.

Set GPRF measurement signal path scenario (standalone or combined)

Get current GPRF signal path scenario

Run a complete measurement: arm it, wait for the instrument to report the acquisition finished, then fetch the results. Prefer this over separate trigger and fetch calls -- INITiate returns as soon as the measurement is armed, so a separate fetch cannot tell whether it is reading this acquisition or the previous one. Results are marked stale if a setting changed after the trigger.

Route a measurement or generator application to a front-panel connector and internal converter, e.g. 'RF1C,RX1'. Routing is per-application: setting it for GPRF does nothing for WLAN, Bluetooth or LTE. A converter serves one application at a time, which is what produces resource conflicts when two technologies run at once.

Report an application's routing scenario and the path this server last applied to it. The connector and converter are not readable from the instrument, so the path is only known if it was set here.

Set GPRF measurement trigger source and threshold

Set GPRF power measurement filter type and bandwidth

Set GPRF generator baseband mode (CW, ARB, etc.)

Set GPRF generator/analyzer RF port connector

Set GPRF analyzer user margin in dB

Turn off all generators and measurements (safe state)

Declare the cable and fixture loss between the CMW connector and the DUT, so levels and measured powers refer to the DUT rather than the instrument. Without this every absolute power reading is wrong by the path loss. Attenuation is PER-APPLICATION -- pass the applications you are measuring with, because declaring it for GPRF does nothing for a WLAN or Bluetooth measurement. Setting it also tightens the safety clamps, which check both the DUT plane and the instrument connector.

Report the external attenuation declared for the generator and analyser paths. Check this before trusting any absolute power measurement.

Set the WLAN measurement trigger source. The instrument defaults to 'IF Power', which waits for the input to cross a threshold and will time out on infrequent bursts such as a beacon. Use 'Free Run' to sample continuously, or 'IF Power' to catch the burst itself. Call cmw_wlan_trigger_catalog for the sources this instrument supports.

List the WLAN trigger sources this instrument supports

Set WLAN repetition to SINGleshot or CONTinuous. The application defaults to CONTinuous, in which it never reports a finished state, so a synchronised measurement requires SINGleshot.

Stop a running WLAN measurement and release its RF converter. A measurement left in RDY still owns its converter, which causes a resource conflict for the next application that needs it.
