SENSe<n>:BANDwidth
Function
Sets the bandwidth.
Program message
SENSe<n>:BANDwidth < bw > [< unit >]

Parameter

Explanation
This command sets the bandwidth to the value specified by <bw>.
In the Program message, the value in Hz or in kHz can be set. However, the
response message value is only in Hz unit.
The bandwidth which can be set is different depending on the optical sensor in
use. The bandwidth is also restricted in “MANUAL RANGE” Mode.
In the following table, the combinations of the measuring range and bandwidth
which are marked with an
×
cannot be set. Set only the combinations which are
marked with a .
When the bandwidth is increased while keeping the level range fixed (moving to
the right in the table below), and the combination becomes
×
; then the level range
is changed automatically to a level range which is marked with .
Example: In the case of MU931421A, set the range to –70 dBm. However,
when the bandwidth is changed from 100 Hz to 1 kHz, the range is
automatically changed to –50 dBm.
