E4
This plug -in is used with mainframe MX-8364A, AN/USM -308V1 or
HP 8690A.
E5
The ME-318/U, ME-314/U and the AN/USM-224 are identical units.
E6
The ME-444/U AC voltage range is 100 microvolts to 330 volts. The
TEMOD replacement item's AC voltage range is 100 microvolts to 300
volts. The ME-444/U should be removed from the field and replaced by
the TEMOD item when no measurement requirement exists above 300
volts.
The SG-1128 has balanced output impedance, 135 and 600 ohm output
E7
impedances and has a calibrat ed output attenuator. The TEMOD item
does not have any of these features. The SG-1128 will be purged by the
TEMOD item where these features are not required. The only known user
that requires these features is the Information Systems Command.
E8
The ME-26D measures AC voltages from approximately 50 mv to 300
volts rms at 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 items 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
E9
rms at 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.
E10
In most applications the TEMOD item will be capable of replacing the PL-
1392. The one technical characteristic of the PL-1392 that exceeds that of
the TEMOD item is the maximum detected bandwidth: for the PL-1392 it
is 3 MHz; for the TEMOD item it is 1 MHz.
The AN/USM-207 and AN/USM-207A when used with converter CV -1921
E11
and CV-1921A have an input sensitivity of 10 mv from 35 MHz to 500
MHz. The TEMOD item has an input sensitivity of 15 mV from 30 to 500
MHz. Units that require the additional 5 mV of sensitivity within this
frequency range should retain authorization for their AN/USM -207/207A's.
The AN/USM-44, AN/USM -44A, AN/USM-44B, TS -510/U, TS-510A/U and
E12
the TS -510B/U are various configurations of the Hewlett Packard Model
608. The TS-510's are the signal generators, while the AN/USM-44's are
The TS-2395 measures envelope delay from 300 Hz to 110 kHz for 56,
E13
75, 135 and 600 ohm circuits. The TEMOD item measures envelope
delay from 200 Hz to 100 kHz for 135, 600 and 900 ohm circuits.
