STANDBY and READY
The STANDBY key is located at the bottom left corner of the front
panel. With the DC power connected, press the STANDBY key
briefly to switch the R&S
EB500 from the STANDBY to the READY

will turn on and only the power switch circuit is being powered. In this state, it is safe
to remove the DC power and disconnect the R&S
EB500 from the AC/DC power
adapter. In READY state, the green LED on the left is on. The R&S
EB500 is ready
for operation. All modules are being powered and the R&S
EB500 initiates its startup
procedure.
