Attenuator (Position)
Set the output attenuator by position.
For the relationship of position to attenuator (dB), refer to the Position vs. Attenuator Table.
The DP-SP3 transmits changed value data after receiving this command.
96H, 02H, ,
00H - 05H (Output channel 1 – 6)
00H - 3FH (-INF - 0dB, see the Position vs. Attenuator Table)
Example of setting Output channel 1 attenuator to -12 dB:
96H, 02H, 00H, 33H
Attenuator (Step)
Set the output channel attenuator positions by the number of steps.
Positions can be varied from the current status by the designated number of steps.
One position varies per step.
The DP-SP3 informs position values changed by step Up or Down.
96H, 02H, ,
00H - 05H (Output channel 1 – 6)
UP: 41H - 5FH (1 step up - 31-step up) ; Example showing 1step Up: 41H
Down: 61H - 7FH (1 step down – 31–step down) ; Example showing 1step Down: 61H)
Example showing 3-step Up of Output channel 1 attenuator
96H, 02H, 00H, 43H
Mute
Set the output channel mute to ON or OFF.
The DP-SP3 transmits changed value data after receiving this command.
97H, 02H, ,
00H - 05H (Output channel 1 – 6)
00H: OFF
01H: ON
Example of setting Output channel 1 mute to ON:
97H, 02H, 00H, 01H
