4080 series Function & Arbitrary/Function Generators –Instruction Manual
40
Check the duty cycle of current pulse output. The returned value is percentage.
VOLTage <amplitude>
Set the amplitude of the currently active waveform. The amplitude setting should be consistent with
the technical specifications. The output amplitude ranges of P_PULSE, N_PULSE, P_DC and
N_DC should be 2mVpp ≤ ampl ≤ 10Vpp in high impedance output setting and 1mVpp ≤ ampl ≤
5Vpp in 50Ω setting. The above value is given based on a DC offset of 0V. If a DC offset is used,
refer to the setting of DC offset described in Chapter 4 in this manual
VOLTage?
Check the output amplitude of current main function output.
VOLTage OFFSet <offset>
Set the DC offset. For the relationship between the DC offset and output amplitude, refer to section
4.5.3.
VOLTage OFFSet?
Check the DC offset of main function output.
OUTPut:LOAD {50|INFinity}
Configure the amplitude display value for 50Ω or high impedance (INFinity) load termination. The
output amplitude should be consistent with the technical specifications.
OUTPut:LOAD?
Read the current load impedance setting of the function generator.
INPUT: FILTER {ON|OFF}
Enable/disable the low pass filter for the counter
INPUT:FILTER?
Read the current “on/off” state of the low pass filter.
INPUT:ATTenuator {ON|OFF}
Enable/disable Set the input attenuator of the counter
INPUT:ATTenuator?
Read the state of the input attenuator (on/off)
*SAV {0|1|2|3|4|5|6|7|8|9|10}
Save as many as 11 input states of the instrument. Among the 11 states, state 0 is used to
automatically store the power off setting of the instrument. States 1~10 are user defined.
*RCL {0|1|2|3|4|5|6|7|8|9|10}
Recall one of the states 0 -10.
RF:STATe <ON/OFF>
Enables/Disables main output
RF:STATe?
Reads the current state of the main output
