Operation and Reference
Linear Frequency Sweeps
In linear mode, either continuous or single sweeps are available. Single sweep is from the
start to stop frequency, where either the start or stop frequency may be the higher value.
To begin a single sweep:
1. Press [Reset/Start] to set output and display to the start frequency
selected and reset the X-Drive ramp.
2. Press [Reset/Start] again to start the sweep.
pie output signal frequency sweeps to the selected stop frequency and remains there. This
frequency appears in the display.
Continuous linear sweeps alternate between up and down-sweeps. A continuous sweep
begins when the [Start] key is pressed. The Cont indicator illuminates while the continuous
^eep IS active. Continuous sweeps may be stopped by pressing the [Start] key or by pressing
[Reset/Start], [Freq], or [Phase] keys. With enhancements turned off, the sweep may stop
when other parameters are changed. With enhancements turned on, the sweep does not stop
for parameter changes that do not affect the sweep (i.e., amplitude or offset changes do not
cause the sweep to stop). Pressing [Amptd Cal], [Self Test], [Asgn Zero 0], or changing the
function stops a continuous sweep. When a sweep stops, the display indicates the frequency
at which the sweep stopped.
Linear Sweep Bandwidth
The m^imum bandwidth is the full frequency range for the function selected. The minimum
bandwidth for each function is as follows:
(10 mHz/s) X (sweep time)
(5 mHz/s) X (sweep time)
(0.5 mHz/s) X (sweep time)
(1 mHz/s) X (sweep time)
fbr sw^p bandwidths of less than 100 times the minimum bandwidth, bandwidth selected
should be an integral multiple of the minimum bandwidth or sweep-time errors and
stop-frequency errors will occur.
Log Frequency Sweep
In either single or continuous log sweep mode, the stop frequency must be
higher than the start frequency and the sweep is up-only (continuous log
sweep is a repetitiye start-to-stop sweep, only). The minimum bandwidth for
log sweep is one decade. Single log sweep is a line-segmented log
approximation in one-tenth decade segments, and continuous log sweep
is a two-segment-per-decade log approximation.
For narrow-band log sweeps, the actual stop frequency may be higher than the
selected stop frequency. The error decreases as sweep time is increased. This
error is minimized by activating enhancements.
