2.2.1.2 Status LEDs
The status LEDs are located above the standby key in the bottom left corner of the front
panel.
They light to indicate the following instrument states:
●
ERROR: An error (e.g. a hardware error) occurred during operation. The error impairs
the correct functioning and must be eliminated before correct instrument operation
can be ensured.
The LED blinks to indicate that the reference frequency is not locked. This happens
e.g. if the R&S CMW500 is switched from internal to external reference while no
external reference signal is available, or if synchronization to the reference signal is
lost. Use the "Setup" dialog to check the frequency and level of the external reference
signal.
See also chapter 4.4.6, "Sync Settings", on page 97.
●
REMOTE: The instrument is controlled via its remote interface.
●
BUSY: The instrument is booted, or a software module is loaded.
●
READY: The instrument is ready for use, the startup procedure is finished.
2.2.1.3 Standby Key
The standby key is located in the bottom left corner of the front panel.
The standby key serves two main purposes:
●
Switch from standby state to ready state in order to initiate the startup procedure
●
Shut down the instrument
The LEDs indicate the standby state and the ready state:
●
Left, green LED:
Indicates the ready state. The R&S CMW500 is ready for operation. All modules are
power-supplied.
●
Right, amber LED:
Indicates the standby state. The standby power only supplies the power switch cir-
cuits and the optional oven quartz (Timebase OCXO, option R&S CMW-B690A). In
this state it is safe to switch off the AC power and disconnect the instrument from the
power supply.
See also chapter 2.1.3.2, "Starting Up and Shutting Down", on page 14.
2.2.1.4 Display, Softkeys and Hotkeys
The R&S CMW500 with selection R&S CMW-S600B, R&S CMW-S600D or R&S CMW-
S600F is equipped with a color display providing control elements for the applications
and output elements for measurement results. Refer to the data sheet for the technical
characteristics of the display.
Softkeys and hotkeys are located in two bars next to the display:
●
The "softkey bar" on the right side consists of 8 softkeys. Pressing a softkey at the
front panel has the same effect as clicking the button to the left of the softkey, using
