The ME-26D measures AC voltages from approximately 50 mv to 300 volts rms at
E8
frequencies from 20 Hz to 700 MHz (different for other versions of ME -26's). The
TEMOD item measures AC voltages from 10 mv to 750 volts rms at frequencies
from 20 Hz to 50 kHz (3 dB bandwidth is 200 kHz). With RF probe, TEMOD item
measures voltages from 100 kHz to 500 MHz with an input level from 0.25 volts to
30 volts rms. Where the TEMOD i tems measurement capabilities do not satisfy the
users measurement requirements, units should retain the ME -26. In all other cases
where the TEMOD item satisfies the measurement requirement, the ME -26 should
be removed from the field. Only known applications where problems have been
reported is when the ME -26 is used to support the AN/GRC-106 and AN/GRC-50.
The ME-30 measures voltages from approximately 100 v to 300 volts rms at
E9
frequencies from 10 Hz to 4 MHz. The TEMOD item measures voltages from 10
mV to 750 volts rms at frequencies from 20 Hz to 50 KHz (3 dB bandwidth is 200
kHz). With RF probe, TEMOD item measures voltages from 100 kHz to 500 MHz
with an input level from 0.25 volts to 30 volts rms. Where the TEMOD items
measurement capabilities do not satisfy the users measurement requirements units
should retain the ME -30. In all other cases where the TEMOD item satisfies the
measurement requirement the ME -30 will be removed from the field.
The TS-585 measures power from 0.2 milliwatts to 5 watts or -10 to +37 dBm with
E24
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.
This item is a Hewlett Packard Model 410C. It can measure dc voltages to 1500
E84
volts; ac voltages of 0.5 to 300 volts from 20 Hz to 700 MHz. The AN/USM-486 can
measure dc voltages to 1000 volts; ac voltages to 750 volts from 20 Hz to 50 kHz
(3 dB bandwidth is 200 kHz). With an RF probe, it can measure voltages from 100
kHz to 500 MHz with an input level from 0.25 volts to 30 volts rms. Use AN/USM-
486 where the additional measurement capabilities of the HP 410C are not
required. Otherwise, retain HP 410C.
This item is a Simpson Model 269 analog volt-ohm -ampere meter. It can measure
E99
DC voltages to 4000 volts, AC voltages to 800 volts, and DC current to 8 amps .
The AN/USM-486 can measure DC voltages to 6000 volts with high voltage probe,
AC voltages to 750 volts, and DC current to 2 amps. Use the AN/USM-486 where
the additional AC voltage and DC current capabilities of the AN/USM-123 are not
required. Otherwise, retain the AN/USM-123.
This item is a Simpson model 260 analog volt-ohm -ampere meter. It can measure
E105
DC voltage to 5000 volts, AC voltage to 5000 volts, DC current to 10 Amps and
-20 to +4.9 dBm. The AN/USM-486 can measure DC voltages to 6000 volts with
high voltage probe, AC voltages to 750 volts, and DC current to 2 amps. Use the
AN/USM-486 where the additional AC voltage, DC current and decibels
measurement capabilities of the ME -450 are not required. Otherwise, retain the
ME-450.
