The TS-2669 measures envelope delay from 100 Hz to 550 kHz for 75,
E14
120, 135, 150, 600 and 900 ohm circuits. The TEMOD item measures
envelope delay from 200 Hz to 110 kHz for 135, 600 and 900 ohm
circuits.
E15
The TEMOD item measures envelope delay from 200 Hz to 100 kHz for
135, 600 and 900 ohm circuits in addition to the following: level, noise,
impulse noise, non -linear distortion, jitter, hits, par, s/n and return loss.
E16
The ME-490 measures jitter and hits.
The 9041 measures level and return loss. It also contains decad e build-
E17
out capacitors.
E18
The TD -1225A(V)2 will not replace the CM -77A/USM in the maintenance
support application for avionics radios AN/ARC -115, AN/ARC-116,
AN/ARC -51, AN/ARC -164 and AN/ARC -186. (The CM -77A/USM has a
down converter while the TEMOD item does not.) In all other applications
the TD-1225A(V)2 replaces the CM -77A/USM.
CP-1101 measures impulse noise only. TEMOD item performs the
E19
following measurements: level (transmit and receive), par, noise and
noise to ground.
TS-3156 measures level and noise. TEMOD item performs the following
E20
additional measurements: par, noise to ground and impulse noise.
ME-22 measures level. TEMOD item performs the following additional
E21
measurements: transmit level, par, noise, noise to ground and impulse
noise.
ME-71 has a receive level range of -70 to +42 dBm from 20 to 500 kHz.
E22
TEMOD item has a level range of -40 to +10 dBm for both transmit and
receive over the range 50 Hz to 110 kHz and performs the following
additional measurements: noise, noise to ground, par and impulse noise.
E23
TS-3157 has a transmit and receive frequency range of 300 Hz to 3.5
kHz. The TEMOD item has a frequency range of 50 Hz to 110 kHz and
performs the following additional measurements: noise, noise to ground,
par and impulse noise.
The TS-585 measures power from 0.2 milliwatts to 5 watts or -10 to +37
E24
dBm with a variable input impedance from 2.5 to 20, 000 ohms. The
TEMOD item measures dBm referenced to only 15 selectable
impedances: 50, 75, 93, 110, 125, 135, 150, 250, 300, 500, 600, 800,
900, 1000 and 1200 ohms. Output is not displayed in watts. In
applications that require a variable input impedance, the AN/USM -486
does not replace the TS -585.
E25
This item is being replaced by the SG-1171. The SG -1288 is also capable
of replacing subject item. Units with SG-1171 will retain it as a standard
LCC A item, while additional requirements will be satisfied by the SG-
1288.
Upper frequency limit of the AN/UPM-84A is 63 GHz. Upper frequency
E26
limit of the AN/USM -489 is 40GHz with mixer supplied (to 220 GHz with
additional Tektronix mixers). If a unit is authorized an AN/UPM-84A and
does not require a frequency range above 40 GHz then the AN/USM -489
can replace the AN/UPM-84A.
