NOTES
The MS462XC VNMS- Direct Receiver Access version
cannot make system measurements without an external
test set that couples power into the reference and test
channels, such as the Anritsu MS4782A. This manual will
discuss calibration and system measurements for the
MS462XX assuming the user understands the need for the
external test set for the MS462XC.
For the MS462XC, the a

connectors on the rear
panel are inputs and normally connected to a MS4782X
Test Set, when used with the ME7840A Power Amplifier
Test System. If a test set is not connected, 50 Ohm termi
-
nations must be used with these connectors.
1-7 EXTERNAL INTERFACES In addition to the visible external interfaces¾keyboard, LCD, and
floppy disk drive¾the MS462XX provides the following interfaces:
q
IEEE488.2 GPIB: Connects MS462XX to an external controller
for remote programming. Connections provides support for the
37XXX Series GPIB command set (as applicable to MS462XX
hardware). It also provides partial support for the Hewlett
Packard 8753D command set. This interface is described in the
MS462XX Programming Manual, Part Number: 10410-00204
q
Dedicated GPIB: Connects external peripherals for network mea-
surement system controlled operations (such as, GPIB plotters,
frequency synthesizers, and power meters)
q
Printer: Provides support for the Think Jet, HPQuietJet, HP
DeskJet, HP LaserJet II, III, & IV Series, and some Epson com
-
patible printers with Parallel (Centronics) interfaces. Requires a
DB25 male to Centronics male printer cable, APN: 2225-6
q
External I/O: Provides input/output (I/O) access for Channel 1
through Channel 4 limits, including pass and fail indications. It
is also used for TTL Out and TTL In (for Sequence feature)
q
Ethernet: Provides network control of the MS462XX using the na
-
tive GPIB command set. This interface is also described in the
MS462XX Programming Manual, Part Number: 10410-00204
