property amplitude: Any: Control the amplitude of the output waveform. Depending on amplitude unit, the unit is Volt (peak-to-peak), Volt (RMS) or dBm. The limits depend on the configured output termination (50 Ohm to High Impedance changes by a factor of 2) and the offset. Supplying out-of-bound values may silently be clipped by the device (float, in V or dBm)

property amplitude_unit: Any: Control the units of the amplitude (string, strict from VPP, VRMS, DBM).

beep(): Causes a system beep.

property beeper_state: Any: Control the state of the beeper (bool).

property burst_mode: Any: Control the burst mode (string, strict from TRIG, TRIGGERED, GAT, GATED).

property burst_ncycles: Any: Control the number of cycles to be output when a burst is triggered (int, strict from 1 to 50000).

property burst_state: Any: Control whether the burst mode is on (bool).

property frequency: Any: Control the frequency of the output waveform. Depending on the output shape, the supported frequency range changes. Supplying out-of-bound values may silently be clipped by the device (float, in Hz)

property offset: Any: Control the voltage offset of the output waveform. This is limited by the amplitude and output termination. Supplying out-of-bound values may silently be clipped by the device. (float, in V)

property output: Any: Control the output of the function generator (bool).

property pulse_dutycycle: Any: Control the duty cycle of a pulse waveform function in percent (float, strict from 0 to 100).

property pulse_hold: Any: Control if either the pulse width or the duty cycle is retained when changing the period or frequency of the waveform (string, strict from WIDT, WIDTH, DCYC, DCYCLE).

property pulse_period: Any: Control the period of a pulse waveform function in seconds (float, strict from 200e-9 to 2e3). The period overwrites the frequency for all waveforms. If the period is shorter than the pulse width + the edge time, the edge time and pulse width will be adjusted accordingly.

property pulse_transition: Any: Control the edge time in seconds for both the rising and falling edges. It is defined as the time between 0.1 and 0.9 of the threshold. Valid values are between 5 ns to 100 ns. The transition time has to be smaller than 0.625 * the pulse width.

property pulse_width: Any: Control the width of a pulse waveform function in seconds (float, strict from 20e-9 to 2e3).

property ramp_symmetry: Any: Control the symmetry percentage for the ramp waveform (float, strict from 0 to 100).

property remote_local_state: Any: Set the remote/local state of the function generator (string, strict from LOC, LOCAL, REM, REMOTE, RWL, RWLOCK).

property shape: Any: Control the output waveform (string, strict from SINUSOID, SIN, SQUARE, SQU, RAMP, PULSE, PULS, NOISE, NOIS, DC, USER).

property square_dutycycle: Any: Control the duty cycle of a square waveform function (float, strict from 20 to 80).

trigger(): Send a trigger signal to the function generator.

property trigger_source: Any: Control the trigger source (string, strict from IMM, IMMEDIATE, EXT, EXTERNAL, BUS).

property trigger_state: Any: Control whether the output is triggered (bool).

property voltage_high: Any: Control the upper voltage of the output waveform. The limits depend on the output termination. Supplying out-of-bound values may silently be clipped by the device. (float, in V)

property voltage_low: Any: Control the lower voltage of the output waveform. The limits depend on the output termination. Supplying out-of-bound values may silently be clipped by the device. (float, in V)

wait_for_trigger(timeout=3600, should_stop=<function Agilent33220A.<lambda>>)

Wait until the triggering has finished or timeout is reached.

Parameters:

timeout – The maximum time the waiting is allowed to take. If timeout is exceeded, a TimeoutError is raised. If timeout is set to zero, no timeout will be used. (default: 3600)
should_stop – Optional function (returning a bool) to allow the waiting to be stopped before its end. (default: <function Agilent33220A.<lambda> at 0x76f1fd0220c0>)
