APPENDIX
These option cards can be used for a variety of applications requiring programmable fre
quency outputs. The RS- 485 model of this card can be operated as an N.8 frequency syn
thesizer.
Depending on your card model number, the outputs are available in different formats:
RS-485 on a pluggable terminal block
TTL square wave on BNC, or
Sine wave on BNC
Each output can be phase-offset between 0-360° in 0.1°-increments.
