1.2.6 Power On and Off
The
DC power connection X1 is located at the top left corner of the
R&S DDF205 rear panel. With the DC power connected, the
R&S DDF205 is in STANDBY or READY state, depending on the
state of the STANDBY toggle switch at the front panel of the
R&S DDF205 when it was last switched off. The standby power is
below 0.8 W.
1.2.7 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 DDF205 from the STANDBY to the READY
state and vice versa. In STANDBY state, the amber LED on the right
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 DDF205 from the AC/DC power
adapter. In READY state, the green LED on the left is on. The R&S DDF205 is ready
for operation. All modules are being powered and the R&S DDF205 initiates its
startup procedure.
