E74
150, 600, 10 k, 20 k ohms; input signal level -120 to +12 dBm; selectivity
filter BW=45, 2300 Hz; portable; internal rechargeable batteries. TEMOD
item input impedance 75, 124, 135, 600, 10 kohms; input signal level -120
to +20 dBm; selectivity filter BW=20, 400, 3100 Hz and C-MSG weighing;

E75
Cushman CE -70 Frequency Selective Levelmeter: Input impedance 75,
124, 135, 600 and 100 kohms (with model 701 bridging probe); input
signal level -129 to +12 dBm; selectivity filter BW=75, 1740, 3100 Hz. CE -
70 may be paired with CE -71 spectrum display and CE -72 signal
generator. TEMOD item input impedance 75, 124, 135, 600 and 10
kohms; input signal level -120 to +20 dBm; selectivity filter BW=20, 400,

Marconi TF2330A Wave Analyzer: Frequency Range 20 Hz to 76 kHz;
E76
input signal level 30 microV to 300 V F.S.; selectivity filter BW=7 Hz.
TEMOD item frequency range is 50 Hz to 32.5 MHz; input signal level
-120 to +20 dBm; selectivity filter BW=20, 400, 3100 Hz, C-MSG weighing.
All makes/models contain signal input connectors and corresponding input
E77
impedance different than those of the TEMOD item (AN/USM -490);
imped ances may be specified for unbalanced, balanced, terminating or
bridging conditions. Typically, wave analyzer input impedances are greater
than those for selective level meters.
No type designator assigned. Commercial make and model number
I1
appears in Type Designator column.
The salient technical characteristics of the potentially replaceable TMDE
I3
that exceed those of the TEMOD item are listed in the appropriate "E"
code. These technical differences listed are the major differences in
performance between the two items; other technical differences may exist
which could prevent replaceability by the TEMOD item. Before a user
adopts the TEMOD item as a replacement, a detailed spec comparison
should be performed.
Item does not have a LIN; however, item is capable of being replaced by
P2
TEMOD item and will eventually be purged by attrition. Unit should take
action to update authorization documents to include TEMOD item. (i.e.,
Objective is to get MTOE's/TDA's updated). Following formal authorization
and requisition, the TEMOD item will be issued.
