Generating clock signal on IFR 1200s
« on: June 14, 2018, 07:36:11 pm »
Greetings!

I'm maintaining a Motorola MTR3000 Base Station Repeater. I've tested it for with every single troubleshooting available in Motorola detailed and basic service manual. Finally what is left is that i recalibrate it providing a clock reference to its SCM board.


Anyway's, i've two service monitor: a HP 8920b and an IFR 1200s. As far as i know both generate signals, but only the 1200s is able to generate Motorola MTR3000 required signal wich is: 10Mhz with 3v peak-to-peak, sine or square wave.

I'm having some difficulty with this 1200s, trying to generate the signal. A helpful tip would be welcome. Is anyone here used to operate this service monitor?

Hi,
     the only way you can get the 10 MHz signal of the level you want is from the Ref BNC socket on the back panel. This connection can be an input or an output. Outputs a 10 MHz  signal normally  but will automatically switch when a 10 MHz  external ref signal applied.

My 8920B will generate 3 volts peak to peak @ 10 MHz out of the duplex port.
