Adjust Operating State; Local Oscillation Mode - Deepace KC901M User Manual

In RF signal source mode, please use the N-port on the left side. The RF generator
has the option of having its output selected as either Port2 or Port1.
Access: Press MODE and then NEXT, finally choose RF SOURCE in the menu.
Audio signal source (AF SOURCE)
Audio Signal Source(AF SOURCE) is for producing a low-frequency voltage signal.
its typical application is to adjust the audio signal paths in devices. Since the audio
signal source can produce a steady output up to 50MHz with various modulation, it
can also be used for adjusting RF circuits under 50MHz.
The Audio signal source actually can be set to a very high frequency (performance
can't be guaranteed). Assisted by the under-sampling output, it can also be used for
adjusting radio station's sensitivity and so on. The AF generator has the option of its
output being selected as the central BNC AF gen output (1Kohm), Port2 or Port1
(both 50 ohms).
Access: Press MODE and then choose NEXT, finally choose AF SOURCE in the
menu.
2.5 Adjust Operation State
On power-on, under the default setting the device will automatically sweep once,
and then turn STOP. Thereinafter, you must restart it by pressing RUN/STOP, then it
keeps sweeping until you push the same to stop. By clicking SHIFT first and then press
RUN/STOP
a secondary function of the RUN/STOP button is activated (shown in the
,
screen the sign "
press RUN/STOP the device will run once only. Re-press SHIFT + RUN/STOP to
terminate this mode.
Single sweeping mode. Instrument sweeps only once with each RUN/STOP
press.
continuous sweeping mode. Instrument will do the constant sweeping. In
the single sweep mode, this sign will also be shown while sweeping.
Stop sweeping. RF circuit's power will be cut entirely.
If the main setting parameters are changed when not sweeping, instrument will
scan once automatically.
NOTice
:
Since there is no warm-up, the result will be less precise in the single sweeping
mode and thus it is more suitable for qualitative analysis. To collect more accurate
data, instrument must be set to "continuous sweeping mode".

2.6 Local Oscillation Mode

There is a Local oscillation mode in each of the following modes: SPEC, S21 and
FIELD. This function is for judging signal imaging.
"); and this is for one-time sweep. In this mode, each time you
