this marker frequency.
2)
When external trigger source is selected:
The terminal is used to receive the external trigger signal, and there is no
sync signal output.
6. Burst Waveform
1)
When the internal or manual trigger source is selected:
Infinite burst: the sync signal is the same as that of the basic
⚫
waveform.
N cycle burst: the sync signal is TTL high level at the start of the
⚫
burst and will change to TTL low level after the specified number of
cycles is finished. For the sync signal, the frequency is the
reciprocal of the Burst Period and the duty cycle is Carrier
Period*Cycles/Burst Period.
Gated burst: the terminal is used to receive the external gate signal,
⚫
and there is no sync signal output.
2)
When external trigger source is selected:
The terminal is used to receive the external trigger signal, and there is no
sync signal output.
Coupling Setting
DG2000 supports frequency, amplitude, and phase couplings. You can set the
frequency deviation (frequency ratio), amplitude deviation (amplitude ratio), or
phase deviation (phase ratio) of the two channels. When the corresponding coupling
functions are enabled, CH1 and CH2 are mutual base sources. When the frequency,
amplitude, or phase of one channel (as the base source) is changed, the
corresponding parameter of the other channel will be changed automatically and
always keeps the specified frequency deviation (ratio), amplitude deviation (ratio), or
phase deviation (ratio) relative to the base channel.
In the channel setting interface, tap the CoupleSet menu label to enter the channel
coupling setting interface.
Frequency Coupling
1. To Enable the Coupling Function
Tap the Freq Cpl parameter selection field to select "On" or "Off" to enable or
disable the frequency coupling function. By default, it is set to "Off".
2. Freq Coupling Mode
Tap the FreqCplMode parameter selection field to select "Deviation" or "Ratio".
Then, tap the Freq Dev or Freq Ratio parameter selection field to input the
