skrf.vi.vna.HP8510C¶

class skrf.vi.vna.HP8510C(address='GPIB::16::INSTR', visa_library='@py', **kwargs)[source]¶

Slightly more sophisticated 8510 driver than the one in vna_old.py, which is preserved for compatibility.

Features: * Chunked Sweep – sweep with any number of points, emulated by sweeping in chunks or list mode if necessary. * Tested with AD007 (a VXI11-compliant GPIB-Ethernet adapter) and pyvisa-py (not dependent on NI VISA or Keysight IO)

Attributes

`averaging`	Averaging factor for AVERON
`continuous`	True iff sweep mode is continuous.
`delay_seconds_before_readback`
`error`	Error from OUTPERRO
`idn`	Instrument ID string
`s11`
`s12`
`s21`
`s22`

Methods

`__init__`	Initialize a network analyzer object
`ask_for_cmplx`	Like ask_for_values, but use FORM2 binary transfer, much faster than ASCII.
`clear`
`close`
`get_frequency`
`get_list_of_traces`	The 8510 doesn't really support multiple traces, so we just list S params.
`get_oneport`	convenience wrapper for get_snp_network enforcing 1-port only
`get_snp_network`	return n-port network as an Network object
`get_ssn`	Get (start_hz, stop_hz, n_points) tuple
`get_switch_terms`	create new traces for the switch terms and return as a 2-length list of forward and reverse terms
`get_traces`	retrieve traces as 1-port networks from a list returned by get_list_of_traces
`get_twoport`	convenience wrapper for get_snp_network enforcing 2-ports only
`one_port`	Performs one or more sweeps as per set_frequency_*, returns network.
`reset`	Preset instrument.
`set_frequency_ramp`	Ramp (fast, not synthesized) sweep.
`set_frequency_step`	Step (slow, synthesized) sweep + logic to handle lots of npoint.
`set_frequency_sweep`	Set the frequency sweep parameters on the specified or active channel
`set_hz`	List sweep using hz, an array of frequencies.
`switch_terms`	measures forward and reverse switch terms and returns them as a pair of one-port networks.
`to_hz`	A simple convenience function to create frequency in Hz if it is in a different unit
`two_port`	Performs one or more sweeps per set_frequency_*, returns network.
`wait_until_finished`
