After power-on, the analyzer is in standby or ready state, (see
on page 16) depending on the state of the STANDBY toggle
switch at the front panel when the instrument was switched off for the last time.
The AC power switch can be permanently on. Switching off is required only if the
instrument must be completely removed from the AC power supply.
1.3.8 Standby and Ready State
The STANDBY toggle switch is located in the bottom left corner of the front panel.
► After switching on the AC power (see
chapter 1.3.7, "Power on and off"
on page 15) press the STANDBY key briefly to switch the analyzer from the
standby to ready state or vice versa.
●
In standby state, the right, amber LED is on. The standby power only supplies the
power switch circuits and the optional oven quartz (OCXO, 10 MHz reference oscil-
lator, option R&S ZVAB-B4, order no. 1164.1757.02). In this state it is safe to
switch off the AC power and disconnect the instrument from the power supply.
●
In ready state, the left, green LED is on. The analyzer is ready for operation. All
modules are power-supplied and the analyzer initiates its startup procedure.
Shock hazard
The instrument is still power-supplied while it is in standby mode.
1.3.9 Replacing Fuses
The DC inputs PORT BIAS at the rear panel are each protected by a fuse IEC 127 - F
250 L (250 mA quick acting).
► To replace the fuses open the fuse holder by slightly turning the lid counterclock-
wise.
Replacement fuses are provided with the instrument.
