Re: Trak Systems
If you wish to use the reader function, you will need a source of IRIG B time
code (1KHz carrier). Switch the front panel switch to Read and connect the
IRIG code to the CODE IN BNC. If you wish to use it as a generator, switch the
front panel switch to GEN, preset the time a

Re: Measuring TV delays
There's more delay involved in a live feed than most people assume. Let's
start with the live feed or remote. Most live feeds with live crowds will use
a 9 - 10 sec delay to avoid FCC issues with language. Then it's usually one
satellite hop (1/4 sec) to get to the br
. Although the Port 2connector is wired for Receive Data (pin
3) it does not appear that the GPS Receiverwill accept any commands.
All commands must be issued over the Port

The Z3805A utilizes Carrier to Noise C/N instead of Signal Strength. Typical
values of C/N are 25 - 55 whereas Signal Strength can range from ~30 - 255.

The BD Systems GPS Control Program communicates with the Z3801A (and other HP /
Symmetricom receivers) exclusively through the scpi command protocol.

The Z3805A has two serial ports, both of which are RS-232. Serial Port 2
broadcasts time of day only and will not accept scpi commands. Serial Port 1
shoudl be used for scpi control.

The Z3805A has two serial ports:
* An
I/O Port (Port 1) 25-pin female DB series connector which provides a serial

* A

Use an analog video distribution amplifier (Grass Valley Group, Leitch, Ross
Video etc). These have between 6 to 8 outputs and will provide a reference to
various test equipment.

Serial Port Servers provide many advantages over serial port cards installed in
a computer. More than one computer on the network can access a serial port,
though not simultaneously, and access can occur over a wireles network. Two
serial port servers I have and use are the Digi Portserver TS
