1 kHz - less than -90 dB.
10 kHz - less than -80 dB.

1 MHz - less than -37 dB.
Crosstalk measurements are made at the common output
with a closed channel terminated by 600 ohms; signal is
applied to channels not selected.
Issued 2.0 ms (5 ms in low speed mode) after the card is
programmed to close a channel; this allows for relay
settling time. T h e rising edge of the encode pulse
typically triggers an external instrument such as a digital
voltmeter.
TTL level, negative-going pulse, 500 mA sink capability.

On power-up, the 53A-334 Card is unaddressed (power
LED lit), and all channels are open (channel LEDs out).
On power-down, the 53A-334 Card has all channels open
(channel LEDs out).
5-volt dc power is provided by a 53 or 63 Series Card
Cage.
