No Gary. I meant Sineman. I'm fully aware of the lineman. That was a bit
overpriced for what it did. We had two Nortel units that we bought ex-telco
that did the same thing elegantly.
The Sineman was a unit that we received a mailed brochure. I'm looking at it
now. The description: " Microproce
The idea of the dual meter unit was to be able to quickly go thru a circuit
without having to touch the meter to change ranges or change to AC or DC. If
you stuck it on a DC circuit it would read that right. If you stuck it on an
AC circuit it would read that.
Also you could read an AC voltage rid

The Mod Box was a great idea during it's time. Only the IFR-1000 at the time
had the provision to use a microphone with a pre-emhasis network. Most all the
service monitors only allowed an internal tone or external audio gen. Some
allowed the mix of both. The Mod box was sort of like a microphon

I'm a late comer to picking up extra Helper Instrument Equipment

Whoa!
Bill actually went through with this? I never seen this as a production item
although the idea of a service bench Analog/Digital voltmeter was something he
was interested in doing. The DMM's A/D section was to go to an integrator and
drive a meter for peaking or nulling. My understanding w
That was an auto ranging voltmeter. They were rather expensive at the time,
compared to nowadays. As I remember it you could select auto range, or lock
it in a particular range.

The SM-512 is a service monitor that covers 1 to 512 MHz if memory
serves correctly. It has a built in Sinadder and Millivolt meter. The
system was designed around a Bearcat scanner. When Bearcat quit making
the scanner, the system was redesigned from scratch and expanded to go
to 1GHz, hence the S

Hi Randy,
You'll be hard pressed to find the Service Manual unless one of
the manual sharks (people selling manuals) has one. The only other
source I've seen for the manual has been one or two of the SM-512
units I've seen up on Ebay in the last two years.

Hi Mike, Best I can find out it is called a service monitor, hence SM
in model no.. Has Sinadder function as well as monitor RX and signal
generator and modulator, deviation, and off frequency detector meter.
