Output Mode and Sample Rate

DG1000Z supports Frequency and Sample Rate output modes.

1 Frequency Output Mode

Press ArbArb 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 (ArbEdit WformMode  “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.

2 Sample Rate Output Mode

Press ArbArb 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 (ArbEdit WformMode  “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.
