ANALOG MODULATION MODE
3-63
Sweep
The sweep capability allows the comprehensive testing of systems, as measurements at single
points will not necessarily give an overall indication of the performance. The sweep function is
specified by the following parameters:
•
Start value
•
Stop value
•
Number of steps
•
Time per step
Up to five individually adjustable markers may be set. Each marker can be turned on and off
separately. Sweep functions available are:
•
Carrier frequency with or without modulation
•
RF level
•
Internal modulation rate
•
LF frequency (if in LF generator mode)
•
LF level (if in LF generator mode).
The sweep can be operated in single shot or continuous modes with the start command triggered
by a key press, an external pulse or GPIB control. Once started, the sweep can be stopped at any
time when the display will indicate the current parameter value. The sweep can be used with
oscilloscopes, X-Y display units and X-Y plotters by connecting the display unit X input to the
SWEEP RAMP output on the rear panel.
A sweep routine is set up as described in the following paragraphs:
