Cable Measurement Commands
The commands in this section provide control of the cable measurements
available in the Serial status mode. You access these measurements differently
depending on whether your waveform monitor has V1.X or V2.X (or latter)
firmware. With either version, you must first enter the Serial mode by sending
the command MENU:SERial. This is equivalent to pressing the SERIAL button
on the front panel.
For waveform monitors with version V1.X firmware, cable and signal strength
commands are active after sending the command SERIAL:MENU STATUS. For
version V2.X firmware, send the command SERIAL:MENU CABLE. This is
equivalent to pressing the side bezel button to select the CABLE menu. Cable
measurements are active only when the SERIAL STATUS menu (V1.X) or
SERIAL CABLE menu (V2.X) are selected.
Use the SLM: commands to select the type of cable your installation uses and to
query the waveform monitor for cable type and length. You can also query for
the computed signal level of a monitored signal. Not all commands work with all
versions of firmware.
SLM:CABle <B8281 | B1694 | B1505> (WFM 601E and WFM 601M Only)
Selects the cable type for use by the Signal Level and Approx Cable Length
measurements. This selection corresponds to the Cable Type selection in the
SERIAL menu. This command works with V1.X and V2.X firmware.
