Code: OP
Reply
Parameter: ................... a
0 = no option
1 = Control Unit R&S GB 890
8 = BCD Interface R&S GC 890
9 = Preselection R&S FK 890H1
11 =VLF>HF Receiver R&S EK 895
12 =VLF>HF Receiver R&S EK 896
13 = IF Converter (100 kHz)

Example 1:
Inquiry of options
Command = rAxxOP??
Æ Reply = rAxxOP1,11?
In VLF>HF Receiver R&S EK 895 the option
'Control Unit R&S GB 890' is installed.
Example 2:
Inquiry of options
Command = rAxxOP??
Æ Reply = rAxxOP9,12?
In VLF>HF Receiver R&S EK 896 the options 'BCD
Interface R&S GC 890' and 'Preselector
R&S FK!890H1' are installed.
Example 3:
Inquiry of options
Command = rAxxOP??
Æ Reply = rAxxOP11,14,15?
In VLF>HF Receiver R&S EK 895 the options
'IF Converter R&S UX 895 (455 kHz)' and 'R&S

A3.8.5 Signal BYPASS
Command syntax:
Code: SA
Parameter: ................... a
Possible entries / replies
0= signal level high (OFF)
1= signal level low (ON)
2= signal level depends on scanning status
(ACTIVE)
low: scanning active
high: no scanning
Note:
The command SA is required, when Motor Se>
lection R&S FK 2850 is connected via the op>
tional 'BCD Interface R&S GC 890' to the VLF>HF
receiver. However, this calls for modifications
on the carrier board, the processor and the in>
terface. The values high and low refer to the
output of R&S GC 890.
Example 1:
Inquiry of status of signal BYPASS
Command = rAxxSA??
Æ Reply = rAxxSA0?
Preselector FK 101 is bypassed.
Example 2:
Cancel bypassed state of Preselector R&S FK101
manually.
Command = rAxxSA1?
Example 3:
Bypass Preselector R&S FK101 depending on
the scanning status.
Command = rAxxSA2?
Once scanning is started the bypassed state of
Preselector R&S FK101 is automatically can>
celled.
