The AN/GRM -50 series has an output of +22.5 dBm (3 volts) into 50
ohms. The SG-1144 and the SG -1170 both have output voltages of
+13 dBm (1 volt) into 50 ohms; the AN/GRM -114A, 0 dBm (0.1 volts)
into 50 ohms. Where the AN/GRM -50 series is used to support AM
radios with high output power that require 3 volts RMS stimulus to
drive audio circuitry (such as the AN/GRC-106), units will retain the
AN/GRM -50's. Units that do not require output voltages above +13
dBm for testing end systems such as the AN/VRC -12 and AN/PRC-
77 radios should purge the AN/GRM -50's with the SG-1144 or SG -
1170 or AN/GRM -114A (also see E36, E37, E54).
This item is on the replacement list of AN/USM-485, SG -1288 and
E83
SG-1171. If item is used for telephone testing applications, replace
with AN/USM -485. If used for general purpose applications, replace
with SG-1288 or SG -1171 (see condition code E25).
This item is a Hewlett Packard model 410C. It can measure DC
E84
voltages to 1500 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 will NOT be replaced by the OS-291/G if it is used with any
