rate.
The sampling rate means the time used to output a frequency point during sample. The output
frequency and sampling rate of the frequency list can be expressed as follows:
List Frequency= Sample Rate
÷
List length
3.15.3 Frequency Data:
A set of frequency data is initialized when power on instrument, from
No.1 to No. 512, each No. are assigned a frequency data from 1kHz to 512kHz like below shown.
NO.1
NO.2
NO.3
NO.4
…………
NO.512
1kHz
2kHz
3kHz
4kHz
…………
512kHz
Below table are a frequency list is composed by 10 frequency data from 100kHz to 10kHz with
step 10kHz. The following steps show you how to create this frequency list.
NO.1
NO.2
NO.3
NO.4
…………
NO.10
100kHz
90kHz
80kHz
70kHz

Then repeat the above steps until last No. 10 and input frequency value 10kHz.
3.15.4 Trigger Source:

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
