Methods

auto_range_enabled()	Whether auto-ranging is enabled
disable_auto_range()	Disable auto-ranging
enable_auto_range([enable])	Enable auto-ranging
get_num_averaged()	Get the number of samples to average
get_power()	Get the current power measurement
get_range()	Get the current input range’s max power
get_wavelength()	Get the input signal wavelength setting
set_num_averaged(num_averaged)	Set the number of samples to average

__init__(visa_inst)

auto_range_enabled()

Whether auto-ranging is enabled

Returns:bool : enabled

disable_auto_range()

Disable auto-ranging

enable_auto_range(enable=True)

Enable auto-ranging

get_num_averaged()

Get the number of samples to average

Returns:

num_averaged : int

number of samples that are averaged

get_power()

Get the current power measurement

Returns:

power : Quantity

the current power measurement

get_range()

Get the current input range’s max power

get_wavelength()

Get the input signal wavelength setting

Returns:

wavelength : Quantity

the input signal wavelength in units of [length]

set_num_averaged(num_averaged)

Set the number of samples to average

Each sample takes approximately 3ms. Thus, averaging over 1000 samples would take about a second.

Parameters:

num_averaged : int

number of samples to average

set_wavelength(wavelength)

Set the input signal wavelength setting

Parameters:

wavelength : Quantity

the input signal wavelength in units of [length]
