Selection Filter
Enables or disables a particular selftest specified with its name. To enable or disable
groups of selftests, use wildcards? (substitutes for any one character) or * (substitutes
for any zero or more characters).
Examples:
"*" enables or disables all selftests
"*EEprom*" enables or disables the EEprom tests for all boards
As an alternative to the selection filter, use the "Enable/Disable All" or "Enable/Disable
Subtree" hotkeys.
Enable/Disable All, Enable/Disable Subtree
Selects all or a current group (subtree) of selftests for execution or clears the current
selection.
4.4.6 Sync Settings
The R&S CMW500 can be synchronized either to its fixed internal reference frequency
or to an external reference.
For multi-CMW setups a system synchronization signal has to be provided by one instru-
ment to the other instruments of the setup.

Frequency Source
Sets the R&S CMW500 to internal or external reference.
"Internal"
The internal 800 MHz reference frequency is generated using a Tem-
perature Controlled Crystal Oscillator (TCXO) or an optional oven
quartz (Timebase OCXO, option R&S CMW-B690A).
A 10 MHz reference signal which is derived from the internal reference
can be tapped at the output connector REF OUT 1 in order to syn-
chronize other devices. The R&S CMW500 then acts as a master, pro-
viding the reference clock for other devices.
