+/-10 Volts analog signal. Resolution 16-bit DAC or .0003
Volts. 3 mA maximum
TTL compatible, but can accept up to +/-12 Volts.
Quadrature phase on CHA,CHB. Can accept single-ended
(A+,B+ only) or differential (A+,A-,B+,B-). Maximum
A,B edge rate: 12 MHz. Minimum IDX pulse width: 80
nsec.
TTL (0-5 Volts) level at 50% duty cycle. 3,000,000
pulses/sec maximum frequency
TTL (0-5 Volts)
2.2K ohm in series with optoisolator. Active high or low requires at
least 2mA to activate. Can accept up to 28 Volts without additional
series resistor. Above 28 Volts requires additional resistor.
Standard configuration is +/-10 Volt. 12-Bit Analog-to-Digital
converter. 16-bit optional.
