Command Line
Use Serial/Network Function F120 to obtain information about the current version of the software
installed in the N.1 Frequency Synthesizer Option Board and to configure the N.1 Frequency
Synthesizer Option Board for frequencies to be generated. To obtain the N.1 Frequency Synthesizer
Option Board Status, enter:
F120<SP>B<N><SEP>S<CR>
where:
2
F
= ASCII character F
120
= function number
<SP>
= ASCII space character one or more
B
= ASCII letter to denote Option Bay number follows
<N>
= Option Bay Number, 1 through 10
<SEP>
= one or more separator characters; either space, comma or tab
S
= ASCII letter to denote that N.1 Freq Synthesizer status is requested
<LT>
= line terminator; for output strings (a carriage return and line feed) for input
strings (a carriage return only)

The XLi Serial/Network port responds with an eight line response similar to the following example:
Sample request:
F120 B2 S<CR><LF>
Response:
F120 B2:<CR><LF>
PART NUMBER 87-8022<CR><LF>
FPGA
184-8016V0001<CR><LF>
N.1 PLL LOCKED<CR><LF> ( or
1 1234 HZ<CR><LF>
2 44444444 HZ<CR><LF>
3 59 HZ<CR><LF>
4 777 HZ<CR><LF>
5
UNLOCKED)
The frequency of one of the output channels may be set as follows:
F120<SP> B<N><SEP><C><SEP><FREQ> <CR>
