CN-471 10:1, 70 ohm 20 dB attenuator
CN-316 10:1, 50 ohm 20 dB attenuator
CN-315 2:1, 50 ohm 6 dB attenuator
CU-439 Impedance Matcher, 50 Ohm to 500 Ohm... used when , the input of the
receiver under test is above 500 Ohms.... out put of the generator is 50
Ohms.

These are all accessory pieces that would be clipped to the cover of a
URM-25 series military signal generator.  The manual for the generator is
available for download here: http://www.kg7bz.com/Manuals.html  and should
have more information.  They are pretty handy (read: necessary) for use with
the generator.... and Fair Radio sells them for about $10 but only with a
URM-25 so they are not that easy to find.
