CONFigure:RFGEnerator:DEMOD:THRESH <value>

RF Demodulator Power Threshold

Syntax:

CONF:RFGEnerator:DEMOD:THRESH <value>

Value Range:

-100 to

100

Threshold value for the power
envelope of the Bluetooth
burst [dBm].

Default Value:

Auto

AUTO

Automatic search for max
peak.

Applicable in
State:

Set: All

Query: All

Description:

This command specifies the threshold value for the power
envelope of the Bluetooth burst when using the ‘burst’
demodulator mode. Hence this is the value used when the
measurement attempts to find the power envelope of the applied
Bluetooth signal.

See also the command: CONF:RFGE:DEMOD:THRESH.

Examples:

CONF:RFGE:DEMOD:THRESH 20

Sets 20 dBm
threshold value

CONF:RFGE:DEMOD:THRESH?

Returns current
