Function
1 AGND - Ground
2 UC_EXT_TRG_IN I External trigger 1 input, 5 V tolerant *)
3 AGND - Ground
4 UC_BUSY O Hardware measurement time
5 AGND - Ground
6 READY FOR TRIGGER O Measurement completed, ready for new trigger
(not available for pulsed measurements)
7 AGND - Ground
8 UC_CH_BIT0 O Channel bit 0;
see
CONTrol:AUXiliary:C[:DATA]
and
OUTPut<Ch>:UPORt[:VALue]
9 UC_CH_BIT1 O Channel bit 1
10 UC_CH_BIT2 O Channel bit 2
11 UC_CH_BIT3 O Channel bit 3
12 AGND - Ground
13 UC_PASS1 O Pass/fail result of limit check 1; TTL Out Pass 1 (see TTL1
Pass / TTL2 Pass )
14 UC_PASS2 O Pass/fail result of limit check 2; TTL Out Pass 2
15 AGND - Ground
16 UC_DRV_PORT1 O Used as drive ports (
OUTPut:UPORt:ECBits OFF
) or
channel bits (
OUTPut:UPORt:ECBits ON
; default)
If used as drive ports, DRIVE PORT i is active while test
port i is the source port.
If used as channel bits, the pin states can be defined using
OUTPut<Ch>:UPORt[:VALue]
.

18 UC_DRV_PORT3 O
19 UC_DRV_PORT4 O
20 AGND - Ground
21 UC_EXT_GEN_TRG O Control signal for external generator
22 UC_EXT_GEN_BLANK I Handshake signal from external generator
23 AGND - Ground
24 UC_FOSW I Control input A, 5 V tolerant
25 UC_TRG2 I External trigger 2 input, 5 V tolerant
*) Feeding in the external trigger signal via the BNC connector Trigger In is equivalent.
