2.11.4 Indication of the IEC-Bus Language (LANGUAGE)
Submenu UTILITIES-SYSTEM LANGUAGE indicates the IEC-bus language and the current SCPI
version.
2.11.5 Reference Frequency Internal/External (REF OSC)
In the internal-reference operating mode, the internal reference signal at a frequency of 10 MHz is
available at the REF socket (rear of the instrument).
Signal level: V
eff
(EMF, sine) = 1 V.
The frequency of the internal reference oscillator can be detuned via the TUNE input (rear of the
instrument). Input voltage range ±10 V, pulling range ±1×10
-6
.
The external detuning is possible in both states of the ADJUSTMENT STATE (ON or OFF) unless
option SM-B1, reference oscillator OCXO, is fitted. If option SM-B1, reference oscillator OCXO, is fitted,
the detuning via the TUNE input is only possible if the ADJUSTMENT STATE selection has been
switched to ON in the UTILITIES-REF OSC menu.
In the external-reference operating mode, an external signal at a frequency of 1 MHz to 16 MHz
(spacing 1 MHz) is to be fed into socket REF. The setting to external frequency is effected in the
UTILITIES-REF OSC menu.
Signal level: V
eff
= 0.1 to 2 V
The message "EXT REF" is displayed in the status line in the header field of the display in the
external-reference operating mode.
