SCA
By resetting an internal jumper, the SCA OUTPUT can be used as an SCA referenced
to the AMP OUTPUT crossing the LOWER LEVEL (E) discriminator or as a Timing
SCA referenced to the leading edge of the amplified preamp signal; shipped in the
Timing SCA mode.
TSCA OUTPUT TIMING –
≈
200 ns from the peak of the AMP OUT signal.
TSCA OUTPUT WALK –
≤±
50 ns for a 50:1 change in the AMP OUTPUT signal
amplitude.
INTEGRAL NONLINEARITY –
≤±
0.25% of full scale range for LOWER LEVEL
(E) and WINDOW (
∆
E).
PULSE PAIR RESOLUTION – With the SCA driven from a rectangular shaped
pulser for LOWER LEVEL (E) thresholds
≥
100 mV, the pulse pair resolution is
≤
500
ns over the full linear range for the DISC (LLD) OUTPUT.
TEMPERATURE DRIFT (E and
∆
E)
−≤±
0.005% of full scale/
°
C (50 ppm).
POWER SUPPLY SENSITIVITY – Both discriminators are referenced to the +12 and
+24 V Bin supplies.
Connectors
SIGNAL CONNECTORS – BNC type.
PREAMP POWER – Rear panel, Amphenol 17-10090.
Power Requirements
+24 V dc – 50 mA
+12 V dc – 160 mA
–24 V dc – 50 mA
–12 V dc – 70 mA
Physical
SIZE – Standard single-width NIM module 3.43 x 22.12 cm (1.35 x 8.71 in.) per
DOE/ER-0457T.
