RIGOL Chapter 2 Front Panel Operations
2-18 DG1000Z User’s Guide
Please refer to “To Output Basic Waveform” to configure the parameters and
output of the channels. This chapter will focus on “Sample Rate”, “Output Mode”,
“Select Waveform” and “Edit Waveform”.
Output Mode and Sample Rate
DG1000Z supports Frequency and Sample Rate output modes.
1
．
Frequency Output Mode
Press Arb

Arb Mode to select the “Frequency” output mode.
In frequency output mode, users can set the frequency or period of the arbitrary
waveform (the setting method please refer to “To Set Frequency/Period”)
while the sample rate can not be changed. The instrument outputs an arbitrary
waveform which is made up of certain points selected according to the current
output frequency.
For arbitrary waveform, frequency output mode corresponds to period edit
mode (Arb

Edit Wform

Mode

“Period”). If the currently selected
arbitrary waveform is in the period edit mode when the state of RealTime
under Edit Wform is “On”, the instrument will switch to frequency output mode
automatically.

．
Sample Rate Output Mode
Press Arb

Arb Mode to select the “Sample Rate” mode.
In sample rate output mode, users can set the sample rate (the points outputted
per second) while the frequency and period can not be changed. The instrument
outputs the arbitrary waveform point by point according to the current sample
rate.
After the sample rate output mode is selected, press SRate to input the desired
sample rate value using the numeric keyboard and select the desired unit from
the pop-up menu.

The range available of the sample rate is from 1μSa/s to 60MSa/s.

The sample rate units available are MSa/s, kSa/s, Sa/s, mSa/s and μSa/s.
Users can also use the direction keys and knob to set the parameter value: use
the direction keys to move the cursor to select the digit to be edited and then
rotate the knob to change the number.
For arbitrary waveform, the sample rate output mode corresponds to the sample
rate edit mode (Arb

Edit Wform

Mode

“Period”). If the currently
selected arbitrary waveform is in the sample rate edit mode when the state of
RealTime under Edit Wform is “On”, the instrument will switch to sample rate
output mode automatically.
