Hi Nick,****

I was given your email address by Don Reaves who said you might have
information or may want or know someone who might want this signal
generator that I received from my father.****

Let me know if you are interested or can you direct me to someone or some
organization that would like it either by purchase or donation.****

Thanks,****

I was wondering if you could provide me some information.  I have acquired
a Signal Generator TS-418C/U from my father.  I was curious what the value
is and I am looking to sell this unit.  My father says it works and I have
a manual for it (copied version).  The tag says that it was manufactured
for “Naval Air Systems Command” by Crescent Communications Corp.  If you
could give my any info regarding this unit or point me in some direction, I
would appreciate it.****

*Cog Serv: USA FSN: 66256694131 AN/URM-49*

*FUNCTIONAL DESCRIPTION*

Signal Generator AN/URM-49 is portable test equipment used with radio and
radar receivers in measuring standing wave ratios, antenna characteristics,
transmission line characteristics, conversion gain, and receiver
sensitivity.

It consists essentially of an rf oscillator, a power supply and rf power
monitor, a modulator section, including a pulse generator, and an output
section.

*RELATIONSHIP TO SIMILAR EQUIPMENT:*

This equipment, formerly known as Signal Generator TS-418/U, is part of
Test Set AN/MPM-15. Both models of this equipment, which supersedes RF
Signal Generator Equipments LAE and LAF, are identical except that the
later model is provided with additional rf shielding.

*TECHNICAL DESCRIPTION:*

*Power Requirement *: 130 w, 115 v ±10%, 50 to 1,600 cy, .9 pf, 1 phase ac

*Frequency** Range*: 400 to 1,000 mc ±1%

*Type of Emission*: am, cw, pm

*Power Output*: 1 mw

*Output Impedance*: 50 ohms

*Attentuation*: .2 μv (-120 db) to .2 v (0 db) ±2%

*Internal Modulation*::

*Rate*: 40 to 4,000 pps

*Width*: .5 to 10 μsec

*Delay*: 3 to 300 μsec

*External Modulation*:

*Pulse*: 40 to 6,000 pps, .5 to 20 μsec, ± 40 to ±70 v

*Sine Waves*: 100 cy to 100 kc at 3 v for 30% modulation

*Sync Out Pulse*: 65 v peak, no load; 42 v peak into 500 ohm load shunted
by 1,500 μμf; 5 μsec (max) width

*Major Units*: TS-418B/U 12 3/8" x 17 5/8" x 13 1/2" 54.5 lbs
