Press
〖
List No.
〗
soft key and set it to 1.
Press
〖
FreqVal
〗
soft key and set it to 100kHz.
Press
〖
NextListNo
〗
soft key and No. will change to 2 automatically and input frequency value to
90kHz.
Then repeat the above steps until last No. 10 and input frequency value 10kHz.
3.15.4 List Mode :
Press
〖
ListMode
〗
soft key and two modes ‘Customs’ and ‘ Random’ could be
selected. In customized mode, a series of frequency value from user’s customized frequency list
will be output in sequence. In pseudorandom mode, a series of random variable frequency value
according to pseudo-random code will be output, the list length is specified value like below
shown:
List Length=2
n
(5≤n≤10)
3.15.5 Trigger Source:
Press
〖
Source
〗
soft key, If Internal selected, the waveform generator takes
internal source and frequency list repeat running. If manual mode selected, the waveform
generator outputs one sweep each time you press
〖
Manual Trig
〗
soft key. If External selected,
generator takes external source, input external trigger source from ‘Trig In / Out’ port in rear panel.
Each effective trigger edge will trigger once frequency list output. The cycle of trigger signal
should greater than cycle of frequency list and like below formula shown:
Trigger signal’s cycle> List length/ sample rate
3.15.6 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.
3.15.7 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
