E49
This item is a HP -432A with option 002.
The AN/PSM-6 series meters will be replaced by the AN/PSM-45 in all
E50
applications except where low temperature operation (below 0 degrees C)
is required. Only known low temperature requirement is for MICOM:
HAWK, -34 to +41 degrees C and AN/TSQ -73, -32 to +40 degrees C.
E51
This item is an HP -8640 which has a built in frequency counter from 20
Hz to 550 MHz. The TEMOD item does not have this capability. Replace
with TEMOD item if counter is not required.
E52
This item is an HP -8640B w/opt 004 which is the avionics option. It also
has a built in frequency counter. The TEMOD item has neither of these
capabilities. If neither capability is required, replace with TEMOD item.
E53
This item is an HP -8640B w/opt 001 which is an internal variable audio
oscillator from 20 Hz to 600 kHz. It also has an internal frequency
counter. The TEMOD item has an internal modulation generator from 20
Hz to 100 kHz; it does not have frequency counting capabilities. Replace
with TEMOD item if frequency counter and audio oscillator from 20 Hz to
600 kHz is not required.
E54
These items are also on the SG-1144's replacement list. If item has not
already been replaced by the SG-1144, and supplies of the SG-1144 are
depleted, replacement item is the SG-1170.
