If enabled, all logic channels use the same threshold and hysteresis settings.
If disabled, 2 channel groups are available, which can use different threshold and hys-
teresis settings: D0 - D3, and D4 - D7.
Parameters:
<ThresCoup> ON | OFF
*RST: ON
LOGic:GROup<m>:TECHnology <ThresholdType>
Sets the threshold value for the selected channel group, or for all logic channels.
Suffix:
<m>
.
1..3
1 = all logic channels D0 to D7
2 = group D0 to D3
3= group D4 to D7
The suffix only takes effect if LOGic:THCoupling is OFF.
Parameters:
<ThresholdType> TTL | ECL | CMOS | USER
TTL: 1.4 V
ECL: -1.3 V
CMOS: 2.5 V
USER: Set the value with LOGic:GROup<m>:USER.
*RST: TTL
LOGic:GROup<m>:USER <ThresUserValue>
Sets the threshold value if LOGic:GROup<m>:TECHnology is set to USER.
Suffix:
<m>
.
1..3
1 = all logic channels D0 to D7
2 = group D0 to D3
3= group D4 to D7
The suffix only takes effect if LOGic:THCoupling is OFF.
Parameters:
<ThresUserValue> Range: -8 to 8
Increment: 1E-3
*RST: 1.4
Default unit: V
LOGic:GROup<m>:THReshold?
Returns the current threshold value.
