HP8560A

class tam.HP8560A(gpib_controller, gpib_id)

property ident

Returns the instrument ID string.

Raises:

socket.timeout If the instrument is unavailable

initialize()

Initialize the analyzer state.

measure_next_pwr()

Measure the power and freq. of the next highest peak.

This assumes that the measure_pwr method has already been called.

>>> sa.vavg = 5
>>> sa.fspan = 0.1
>>> sa.ref_level = 10.0
>>> sa.measure_pwr(250.0)
(2.732128, 250.000166)
>>> sa.measure_next_pwr()
(1.986321, 250.050134)

Note that if the analyzer cannot find another peak the cal to measure_next_pwr will return the power and frequency values for the first peak.

Returns:

A tuple of two floats with the power of next highest peak being first and the second being the frequency of the peak.

measure_pwr(freq)

Measure the power at a specified frequency.

This assumes that the relevant spectrum analyzer configuration has already been set. This would include: ref. level, freq. span, vavg, detector mode. For exaample:

>>> sa.vavg = 5
>>> sa.fspan = 0.1
>>> sa.ref_level = 10.0
>>> sa.measure_pwr(250.0)
(2.732128, 250.000166)

Parameters:

freq (float) – The centre frequency to make the measurement (in MHz).

Returns:

A tuple of two floats with the measured power being first and the frequency of the marker being the second.
