R&S ESU Preparing for Use
Preparing for Operation
➢
Start the self test with the SETUP key, SERVICE – SELFTEST softkeys. Once the
instrument modules have been checked successfully, the message Selftest Passed will
appear.
Once both steps have been completed successfully, the instrument will be ready for operation.
2.1.7 Switching Off the R&S ESU
➢
Press the ON/STANDBY key on the front panel.
The R&S ESU will store the current settings on the hard disk and then shut down the
software. Once the operation has been completed, the power supply unit will be switched
to STANDBY and the yellow LED will come on.
➢
To completely disconnect the instrument from the AC power supply, change the power
switch on the rear panel to position O.
The self alignment does not need to be repeated every time the
instrument is switched on, because the instrument saves the values
and loads them during booting automatically. A self alignment is
recommended if the instrument is used at a temperature that differs
considerable (more than 10°C) from the temperature present at the last
self alignment.
The self test also does not need to be repeated every time the
instrument is switched on. It is necessary only when instrument
malfunction is suspected.
Shock hazard
In standby mode, the AC supply voltage is still present on the instrument.
• The main power switch on the rear panel also interrupts the power
supply of the OCXO (optional) inside the instrument. When you
switch the instrument back on, be sure to adhere to the extended
warm-up phase.
• If you switch off the instrument by using the power switch or by
disconnecting the power supply connector, it is not possible to save
the current instrument settings on the hard disk. In this case, the last
settings that were stored on the hard disk will be loaded when you
switch the instrument back on.
