Note:
In all menus (Frequency counter, Modulation, Store & Recall ), typing "O" and "K" validates the choice made and takes
you to the next step. Therefore, as long as you have not validated with "O" and "K", you can always come back to
an entered numeric value.
Example for the Modulation function (Fig. 16) :
Note: Only the left column is shown during RS-232 communication; the comments in the right column have been added
to detail the various steps.
Explanation:
Typing "4" "0" "?" returns the generator output frequency, here 1kHz.
Typing "5" "0" "Enter" gives access to the Lin sweep menu (see table).
Typing "O" "K" (line 5) validates the selected modulation.
The first entry of "2" "." "5" "K" for the F Start frequency (line 7) is received by the unit and displayed.
At this time, it is still possible to change the entry (line 8) by setting 2.3 kHz. Typing "O" "K" (line 9) validates this
choice and the unit displays 2.300 kHz on the same line.
Then enter FStop and Rate (the same way as FStart).
The unit returns " RUN lin sweep " to indicate that the modulation is active.
RS-232 transmission protocol reminder:
- Data rate: 9600 bauds (bits per second)
- No parity.
- 1 stop bit.
- 7-bit ASCII alphanumeric data transmission.
