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 ampli-
fied 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
