Features
The Model 940A is a powerful diagnostic tool for analyzing time-
codes in time sensitive instruments. IRIG-B, DCF77 and 1 PPS
signals can be received and evaluated to verify correct operation.
These signals may also be sourced from the 940A to verify opera-
tion of the receiving equipment.
Operating on four Li-ion batteries, the 940A can run continually
for about 12 hours with about 80 percent backlight brightness, and
for about 24 hours at 20 percent brightness. Included in a 940A kit
are the following: USB charger/power supply, USB Cable, 8 feet of
RG-58 with BNC connectors, quick setup guide, and several cable
adapters to match a variety of wire types and connectors.
The 940A features two timing input ports, one timing source
output port, a mini USB charging port, variable output flashlight,
speaker and auxiliary port.
Available input signals are unmodulated IRIG-B, modulated
IRIG-B, IRIG-B Manchester, 1 Pulse Per Second and DCF77.
Three different load conditions are available, which are Load Off,
100 Ohm Load and 50 Ohm Load.
Special Features
Model 940A is designed to provide both a pictorial view and a
description of signals connected to either Input 1 or Input 2. It
also provides a method to compare two signals connected to Input
1 and 2.
A timing source output is also available to verify devices re-
ceiving these signals. Available timing output signals include un-
modulated IRIG-B, modulated IRIG-B, 1 Pulse Per Second and
DCF-77.
