R&S ESU
General Service Functions
INPUT RF The INPUT RF softkey switches the input of the R&S ESU to the input connector
(normal position).
After PRESET, RECALL or R&S ESU power on, the INPUT RF is always selected.
Remote command:
INPUT CAL The INPUT CAL softkey switches the RF input of the R&S ESU to the internal cali-
bration source (128 MHz) and activates the data entry of the output level of the cali-
bration source. Possible values are 0 dB and –30 dB.
Remote command:
ENTER The ENTER PASSWORD softkey allows the entry of a password.
PASSWORD
The R&S ESU contains a variety of service functions which, if incorrectly used, can
affect correct operation of the R&S ESU. These functions are normally not accessi-
ble and are only usable after the entry of a password (see instrument service man-
ual).
Remote command:
CAL GEN 128 The CAL GEN 128 MHZ softkey selects a sinusoidal signal at 128 MHz as output
MHZ signal for the internal calibration source. The internal pulse generator will be
switched off.
Remote command:
CAL GEN This softkey switches the internal pulse generator on and allows the pulse frequency
COMB PULSE to be entered.
Available pulse frequencies are 10 kHz, 62.5 kHz, 100 kHz, 1 MHz, 128 MHz, and
640 MHz.
Remote command:
COMMAND The COMMAND TRACKING softkey activates or deactivates the SCPI error log
TRACKING function. All remote control commands received by the R&S ESU are recorded in
the following log file:
D:\R_S\instr\log\IEC_CMDS.LOG
Logging the commands may be extremely useful for debug purposes, e.g. in order
to find misspelled keywords in control programs.
If this softkey is activated, the R&S ESU becomes slower.
