AFG2ENCoder subsystem

:DTMF:STANdard <string> :DTMF:STANdard?

These commands set/query the standard applied to the encoded data. The standard affects the types of frames that can be sent, the range of valid channel numbers, the encoding of the frame data, and the interpretation of received frames.

Syntax

AFG2:DTMF:STAN ‘Bell’

AFG2:DTMF:STAN?

Screen/field equivalent

AFG2:DTMF:STAN controls the Standard field on the SIGNALING ENCODER screen when the Mode field is set to DTMF.

:DTMF:TWISt <real number> :DTMF:TWISt?

These commands set/query the ratio of amplitudes (in dB) between the high frequency and low frequency tone in each DTMF pair. A positive twist value indicates a higher amplitude for the high frequency tone. A negative value indicates a higher amplitude for the low frequency tone.

Twist and pre-emphasis affect the relative levels of the high and low tones within each symbol (tone pair). See the “Twist and Pre-emphasis” in the Reference Guide for details about the interactions of twist and pre-emphasis.

This command utilizes the “Real Number Setting Syntax” on page 299, but does not use the :INCR or :STATe commands.

Syntax

AFG2:DTMF:TWIS <real number>

AFG2:DTMF:TWIS?

Screen/field equivalent

AFG2:DTMF:TWIS controls the Twist field on the SIGNALING

ENCODER screen when the Mode field is set to DTMF.
