Note 1: Outputs will drive a minimum of 4.0V into a 1K resistor to ground, or a
maximum of 0.4V into a 1K resistor to +5V.
All Pulse Rates are 50/50% duty cycle, positive edge on-time.
* Input Threshold (LOSS) is adjustable from 0.5 to 10V P-P with a carrier
frequency of 100Hz - 100kHz.
B. MULTICODE DC CODE OUTPUT (BNC J4)
This output produces a DC level shift serial code that contains the time value
within the TM7000. It is generated by the
Multi-Encoder section. The time code
format is determined by front panel menu selection.
The DC code generated can be IRIG A, IRIG B, IRIG G, NASA 36, XR3, 2137
or AN/GSQ-53 as selected by the Output Code Menu. The time encoded may
come from either the generator or the translator. Codes may be “re/generated”
from the translator at multiple speeds.
