8.2.7.2 [SENSe:]{FREQuency|PERiod}:VOLTage:RANGe:AUTO
Description:
Enable or disable autoranging for frequency and period measurements.
This parameter is shared between frequency and period.
The autoranging range can be adjusted down to less than 10% of the range and can be adjusted upwards to more
than 120% of the range.
Syntax:
[SENSe:] {FREQuency|PERiod}:VOLTage:RANGe:AUTO {ON|OFF}
[SENSe:] {FREQuency|PERiod}:VOLTage:RANGe:AUTO?
Parameters:
{ON|1|OFF|0}
Example:
FREQ: RANG: AUTO ON
8.2.7.3 [SENSe:]{FREQuency|PERiod}:RANGe:LOWer
Description:
Sets the AC bandwidth used to detect signals during frequency and period measurements.
This parameter is shared between frequency and period.
The instrument uses three different AC filters that allow you to optimize low frequency accuracy or reduce AC
settling time after changing the input signal amplitude. Based on the cutoff frequency specified by this command,
the instrument selects a slow (3 Hz), medium (20 Hz) or fast (200 Hz) filter. Specify the lowest frequency you
want to encounter. Lower frequencies result in longer settling times.
Syntax:
[SENSe:] {FREQuency|PERiod}:RANGe:LOWer {<filter>|MIN|MAX}
[SENSe:] {FREQuency|PERiod}:RANGe:LOWer? [{MIN|MAX|DEF}]
Parameters:
<filter>:{3|20|200}. Default: 20
Example:
FREQ: RANG: LOW 200
8.2.7.4 [SENSe:]{FREQuency|PERiod}:APERture
Description:
Set the aperture time (gated time) for frequency and period measurement.
This parameter is shared between frequency and period.
The larger the aperture time, the higher the measurement accuracy and the lower the measurement speed.
Syntax:
[SENSe:] {FREQuency|PERiod}: APERture {<seconds>|MIN|MAX}
[SENSe:] {FREQuency|PERiod}: APERture? [{MIN|MAX|DEF}]
Parameters:
<seconds>:{10m|100m|1}
Example:
FREQ: APER 100m
8.2.7.5 [SENSe:]FREQuency:SECondary
Description:
Select the auxiliary measurement function for the frequency measurement.
Please use DATA2? to read auxiliary measurement results.
Syntax:
[SENSe:]FREQuency:SECondary {OFF|BEForemath|ACV|PERiod}
[SENSe:]FREQuency:SECondary?
Parameters:
{OFF|BEForemath|ACV|PERiod }
