50 Hz

Sets the post demodulation high pass filter to 50 Hz. It is a 2-pole Butterworth filter,

its 3 dB cutoff frequency is 50 Hz.

Example

:LORA:HPF HPF50

300 Hz

Sets the post demodulation high pass filter to 300 Hz. It is a 2-pole Butterworth

filter, its 3 dB cutoff frequency is 300 Hz.

Example

:LORA:HPF HPF300

400 Hz

Sets the post demodulation high pass filter to 400 Hz. It is a 10-pole Butterworth

filter, its 3 dB cutoff frequency is 430 Hz.

Example

:LORA:HPF HPF400

Manual

Selects the user-defined post demodulation high pass filter. It is a 5-pole

Butterworth filter, its 3 dB cutoff frequency can be changed through the

“[:SENSe]:LORA:HPFilter:MANual[:FREQuency] <freq>” command.

Example

:LORA:HPF MAN

User-defined Highpass Filter

Sets up a post demodulation high pass filter manually. The filter is a 5-pole

Butterworth filter.

Remote Command

[:SENSe]:LORA:HPFilter:MANual[:FREQuency] <freq>

[:SENSe]:LORA:HPFilter:MANual[:FREQuency]?

Example

:LORA:HPF:MAN 500 Hz

:LORA:HPF:MAN?

Notes Adjusts the cutoff frequency of the user-defined high pass filter
