62 ST-133/ST-133A Controller Manual Version 2.H
Outputs
Note: See Appendix B, PTG Module, for information about the PTG connectors.
VIDEO: 1 V pk-pk from 75 Ω, BNC connector. Either RS-170 (EIA) or CCIR standard
video as specified when system was ordered. Requires connection via 75 Ω cable
that must be terminated into 75 Ω.
: TTL output (BNC) for monitoring camera status. TTL low when CCD is being
read; otherwise high. Alternative signal to Shutter Monitor as selected by internal
jumper or software (see note on page 20). Default selection is SHUTTER
MONITOR.
SHUTTER MONITOR: Alternative signal to
as selected by internal jumper or
software (see note on page 20). Precisely brackets shutter-open time (exclusive of
shutter compensation) and can be used to control an external shutter or to inhibit a
pulser or timing generator.
: TTL output (BNC); marks start of first exposure. When run is initiated,
remains high until completion of cleaning cycles preceding first exposure, then goes
low and remains low for duration of run.
SERIAL COMM: Data link to computer via proprietary cable connected to this 9-pin
“D” connector. Cable lengths to 165 feet (50 m) available.
A/D Converters
The ST-133 or ST-133A is available in a number of different configurations. The
configuration provided for a specific order is determined primarily by the choice of
detector specified at the time of purchase. With some configurations it is possible to have
two A/D converters installed. With others there can only be one. Both 12- and 16-bit
converters are available at speeds as high as 1 MHz. Not all converters are available for
all detectors. Some converters run at one speed only. Others can operate at more than one
speed as selected in software. Low-speed operation gives better noise performance; high-
speed operation allows faster data acquisition.
Readout Rate: A function of the installed converter. Speeds as high as 1 MHz (12- and
16-bits) and as low as 50 kHz are currently available.
Linearity: better than 1%.
Readout noise: 1-1.2 counts RMS on standard controllers.
Exposure (integration) Time
5 msec to 2.3 hours (full frame or frame transfer).
