HINT
It is recommended that ordinarily the bandwidth set-
ting be selected as “AUTO.” When using the MT9812B
with an arbitrary specified fixed bandwidth, the mea-
surement value can contain some error.
SENSe<n>:FILTer:BPASs:FREQuency
Function
Sets the modulation frequency.
Program message
SENSe<n>:FILTer:BPASs:FREQuency CW | < freq > [< unit >]
SENSe<n>:FILTer:BPASs:FREQuency?
Response message
< freq >
Parameter
< freq >
:= {0, 270, 1000, 2000} (Unit: Hz)
< unit >
:= {HZ, KHZ}
Explanation
This command sets the modulation frequency of the incident light to be measured.
When the units of the <freq> are omitted, they are set in Hz unit. When the units
are specified with the value of the <unit>, it is set in the specified one.
For 0 Hz, it is set as CW.
In the Program message, the value in either Hz or kHz can be set. But the re-
sponse message value is output only in Hz unit.
