3.15.5 Trigger Edge:
Press
〖
Slope
〗
soft key to select the effective edge of external signal and
make sure set it under external trigger mode to ensure it is effective.
When the rising edge is selected, the frequency list sweep will start when trigger signal changes
from 0 to 1.
When the falling edge is selected, the frequency list sweep will start when trigger signal changes
from 1 to 0.
3.15.6 Trigger Output:
Press
〖
Trig Out
〗
soft key to select output mode of the trigger signal.
The setting of trigger output will be available when in Internal and Manual trigger mode. If Off is
selected, there is no trigger signal at output port. If rising edge is selected, the trigger signal
changes from 0 to 1 when frequency list sweep starts. When frequency list output finish, the
trigger signal will change from 1 to 0. If falling edge is selected, the trigger signal changes from 1
to 0 when frequency list output starts. When frequency list output finish,, the trigger signal from 0
to 1.
3.15.7 Sync Output:
The cycle of sync signal equals to the time of one frequency list sweep
process. The rising edge of sync signal corresponds to the start frequency point of frequency list,
pulse width of sync signal equals to half of frequency list process. If external or manual trigger is
selected, the sync signal will be determined external trigger or manual trigger signal.
3.15.8 List storage
: If you store the frequency lists to RAM storage, it will be lost once power off.
If you want to save current frequency list, make sure save it to FLASH storage.
Press
〖
List Store
〗
, create a document named
Freq_data1.freq
(there is no need to input expanded
name because instrument will add it automatically.), and press
〖
Save to this file
〗
to save it. It is a
binary system document, so you can store many such documents and recall it any time.
3.15.9 List recall
: After entering frequency list interface, if you’ve stored it earlier, you can find it
Freq_data1.freq
by pressing
〖
List Recall
〗
, and then press
〖

, you can
recall the stored list file.
3.16 Arbitrary Waveform
When Direct Digital Synthesis (DDS) technique is used to output the built-in waveform, the
