VM700T Option 01 (NTSC) & Option 11 (PAL) User Manual 1-1
Getting Started
The VM700T Video Measurement Set is a multifunction television test and
measurement device with an easy-to-use interface. The VM700T combines the
functions of a waveform monitor, vectorscope, automatic measurement set, and
noise measurement set in a single instrument. Input signals can be obtained from
live TV broadcast or generated by test equipment. The VM700T can be operated
by using its front-panel controls or by using one of the rear-panel RS-232C ports,
or the GPIB port if Option 48 is installed, to send it commands.
The measurement set can be operated as an NTSC-standard instrument
(Option 01), a PAL-standard instrument (Option 11), or as a dual-standard
instrument when both options are included.
The measurement set functions as a waveform monitor when its Waveform
front-panel button is pressed. Waveform monitor operation is described
Waveform Mode on page 3--1.
The measurement set functions as a vectorscope when its Vector front-panel
button is pressed. Vectorscope operation is described in Vector Mode on
page 3--17.
When the Measure front-panel button is pressed, a list of available measurements
is displayed. A general description of Measure mode operation is given in
Measure Mode on page 3--21. Detailed information about individual measure-
ments is included in the VM700T Option 01 NTSC Measurements User Manual
and the VM700T Option 11 PAL Measurement User Manual. Consult either of
those manuals for more information about individual measurements. Measure-
ment provided with additional installed options are described in the user manuals
supplied for the options.
When the Picture front-panel button is pressed, the VM700T functions as a
low-resolution picture monitor. This display is to assist you in identifying the
input source for other operational modes. Picture mode operation is described in
Picture Mode on page 3--23.
When the Auto front-panel button is pressed, the VM700T cycles through the
selected set of automated measurements. Refer to page 3--25 for a general
description of Auto mode operation. Detailed information about individual
auto-mode measurements is included in the VM700T Option 01 NTSC Measure-
ments User Manual and the VM700T Option 11 PAL Measurements User
Manual. Consult either of those manuals for more information about individual
measurements.

Getting Started
1-2 VM700T Option 01 (NTSC) & Option 11 (PAL) User Manual
The VM700T Video Measurement Set features the ability to record sequences of
operations (functions) and execute them by touching a soft key on the front
panel. See the VM700T RS-232 Interface Programmer Manual for details on
how to record, edit, and execute functions. The functions can also be called
remotely once they have been created.
The measurement set is capable of being remotely controlled. You can operate
the instrument using a computer or terminal connected through a rear-panel
RS-232C port. See the VM700T RS-232 Interface Programmer Manual for
information on remote programming and operation. If Option 48, the GPIB
interface, is also installed, the measurement set may be operated remotely
through the GPIB port. See the VM700T Option 48 GPIB Interface Programmer
Manual for information about GPIB remote control.
An added display option is available for the VM700T. Option 74 provides a
display module with a white phosphor CRT instead of the standard green
phosphor when a VM700T is ordered with the option.
The display can be viewed on an external VGA monitor connected to the rear
panel VGA output connector.
The user manuals for the VM700T Video Measurement Set and its options are
applicable to the VM700A with either the VMTB or the VMTX turbo upgrade
installed.

VM700T Option 01 (NTSC) & Option 11 (PAL) User Manual 1-3
Installation
This section contains information about preparing the VM700T Video Measure-
ment Set for operation.
Power Requirements
The measurement set operates with line frequencies of 50 Hz or 60 Hz, over two
line voltage ranges. The nominal setting of the low voltage range is 115 VAC.
The nominal setting of the high voltage range is 230 VAC.
There are two power switches on the measurement set; one is on the rear panel to
the right of the power cord receptacle, and one is on the front panel. Both must
be on to operate the instrument. The rear-panel switch is the master power
switch. The switch on the front panel remotely enables the voltage supply
outputs.
WARNING. Dangerous voltages are present within the Power Supply module
when the rear-panel power switch is on, regardless of the position of the
front-panel power switch. Do not operate the measurement set with any covers
removed. Refer all servicing of the instrument to a qualified service person.
The voltage range selection switch and fuse holder are located in the lower left
corner of the rear panel (see Figure 1--1). The measurement set is shipped from
the factory set for the operating voltage of the destination nation (115 VAC or
230 VAC). If the setting is not correct as received, it must be changed before
connecting the power cord to the power source. Simply set the voltage range
selection switch (located on the rear panel of the measurement set) to the correct
position for operation.
CAUTION. When changing the line voltage selector switch you must also change
the fuse to provide proper protection for the operating voltage in use. The 3A
slow-blow fuse provides the proper protection in the 230 VAC range and the 6A
slow-blow fuse provides protection for operation in the 115 VAC range.
A detachable three-wire power cord with a three-contact plug is provided with
each instrument for connecting to both the power source and protective ground.
The protective-ground connector in the plug connects (through the protective-
ground conductor) to the accessible metal parts of the instrument. For electrical-
