Output Phase Setting; Frequency Sweeping Function - PeakTech 4055 MV Bedienungsanleitung

4.3. Output phase setting

* Under continuity function, press 【Menu】to display output phase value, input phase value with numeric
keys or adjusting knob, there are only two output phase values, 0 and 1.
* When setting the phase as 0, the phase of signal from 《OUTPUT》port and is the same with the one of
signal from《SYNC》port，while when setting the phase as 1, the two are opposite.

4.4. Frequency sweeping function

In frequency sweep, the output frequency changes from the start frequency point to the end frequency
point according to the setting sweep time. Users may sweep within the whole frequency range. During
this process, the phase of output signals is continuous. All the 16 kinds of waveform could be swept, of
course it makes no sense to sweep DC or noise. Linearity frequency sweeping is similar with ramp
frequency modulation, with the difference of, frequency sweeping does not use modulation waveform, but
continuously output a series of discrete frequency points according to certain time interval.
Press【Sweep】key and the generator enters frequency sweeping function.
4.4.1 Start and end frequency:
* Press【Menu】key to light "Start" letter and then set start frequency point.
* Press【Menu】key to light "Stop" letter and then set end frequency point.
* If the end frequency value is more than the start frequency value, the sweep is positive from lower
frequency to higher frequency, increasing step by step from the start frequency to the end frequency and
then return to the start frequency.
* If end frequency value is less than the start frequency value, the sweep is opposite from higher frequency
to lower frequency, decreasing step by step from the start frequency to the end frequency and then return
to the start frequency.
4.4.2 Sweeping time:
* Press【Menu】-key to light "Time" letter and then set sweep time value.
* Sweep time means the time of sweeping from the start frequency point to the end frequency point.
* The sweep time of every frequency point is the same, so the longer the sweep time is, the more
frequency points are swept, the less the step of the frequency point is, and the finer the sweep is.
* The shorter of the sweep time is, the less frequency points are swept, the more the step of the frequency
point is, and the rougher the sweep is.
