RCal Software – Configuration
Left-Panel Controls
Cal Group:
Stores and groups combinations of user-created calibration states. This is useful for
test setups involving multiple external paths that multiplex into a single output; each path may
need its own individual calibration. The desired Cal Group can be specified here.
Cal Input:
Specifies the desired input for instruments that have more than one input. Each Cal
Group can only support one Cal Input at the same time. If multiple inputs are desired, create a
Cal Group for each input.
Calibrate Checked Rows:
Starts the RCal calibrations for each selected row according to all
user-specified parameters. (See
“Configuration Table Overview” on page 10
for information on
how to set calibration parameters).
Copy From Cal Group:
Allows you to import Cal Group settings into the current Cal Group. This
is useful for calibrating text fixtures that use the same parameters across multiple signal paths.
Apply Cal Group:
Applies all active calibration states for the selected Cal Group.
Select Calibrator:
Selects the RCal module for use. A single signal analyzer can have multiple
RCal modules connected to different ports, but only one module can be used and controlled at a
time. The RCal Model and Serial numbers will appear below this tab.
RCal Reference:
Selects whether RCal is using its internal 100 MHz clock or is locked to an
external 10 MHz reference. The default (and strongly recommended) setting is to use an external
reference in order to synchronize the RCal module with the signal analyzer for complex
calibrations.
Identify RCal Module:
Identifies the active RCal module. If multiple RCal modules are
connected to the signal analyzer, touching this key will cause LEDs on the active unit to flash.
