The AN/GSM -45 can perform the following tests: continuity, RF
attenuation and insulation breakdown. The range of the instrument in the
RF attenuation test is 0 to -102 db. The TEMOD item can perform the
TEMOD item has a range in the RF attenuation test of 0 to -50 db. The
TEMOD item does not measure insulation breakdown. If the user requires
an insulation breakdown test or an RF attenuation test from -50 to -102
db, the TS-4165 does not replace the AN/GSM-45. In all other cases,
replace the AN/GSM -45 with the TS-4165.
The HP -339A has a built in audio oscillator while the TEMOD item does

not. Replace the 339A with the TEMOD item if the audio oscillator is not
required.

The AN/USM-223 will be replaced by the AN/PSM-45 in all applications
except where it is used to perform mai ntenance on the UH-60A Black
Hawk. UH-60A Black Hawk maintenance requires a meter that measures
"smoothness during rotation of various potentiometers as well as linear
voltage readings. In these cases, the Simpson 260-7 series, NSN

The HP -3780 bit range is from 1 Kbps to 50 Mbps where the
TS-4281()/G's bit rate is from 75 bps to 13 Mbps.
E91
The TS-3641 and TS-3642 both have a TTL impedance of 150 ohms
input/output where as the TS -4281()/G has a TTL impedance of 75 ohms
for both the unbalanced output and the unbalanced input along with an
auxiliary interface with a 50 ohm TTL output.
E92
The TS-3642 specifies bipolar 75 ohm unbalanced input with -25 to -30
dBm, bipolar 75 ohm balanced input with +5 to -15 dBm, bipolar 75 ohm
unbalanced output with -72 dBm, and bipolar 75 ohm balanced output
with +23, +10, and 0 dBm switch selectable levels which are not specified
in the TEMOD item.
E93
Replace with the TEMOD item if the requirement is not for battery
operated and weight and size are not of critical importance. TEMOD item
will not exceed 35 lbs.
E94
The IDS 1200 contains bias distortion measurement capabilities which
are not available in the TEMOD item.
E95
The AYDIN 604M has a bit rate of 20 Mbps internal and 25 Mbps external
where the TEMOD item has a bit rate capacity of 13 Mbps.
E96
Not used.
The AN/URM -182 and AN/URM -182A are very small light, and rugged
E97
instruments used primarily with mobile, airborne and pack-carried
AN/URM -182, and AN/URM -182A in certain cases (see cc: E1).

The upper frequency limit of the TEMOD item is 1000 MHz with the
elements supplied. Other elements can be ordered if there is a need
above 1000 MHz.
