VM5000
measurement and high frequency timing
measurements. Utilizing RS-232 control,
the VM5000 automatically selects either
low frequency or wideband mode as
required by the parameter being measured.
Incorporating a full 1 GHz of bandwidth,
with optimized return loss in wideband
mode, the MIU delivers un-matched speed,
accuracy and convenience in testing PC
graphics signals.
Standard GPIB Remote Control
and LAN Connectivity
A fast and reliable GPIB Port compliant to
IEEE 488.2 is standard on the instrument
with selectable controller or talk/listener
modes. A fully documented oscilloscope
GPIB remote command set and simplified
video command set enable all of the
instrument capabilities accessible via the
user interface to be automated via GPIB
remote control.
Network connectivity is provided with
a LAN port supporting 10Base-T and
100Base-T. This enables video test reports
or data stored on the hard drive to be
accessed via the network. Network remote
control can be accomplished via the
Tektronix AD007 GPIB to LAN adapter
accessory, available separately. TekVISA ™
is functional for LAN remote control of the
oscilloscope commands.
Complete Oscilloscope
Functionality
Recognizing the need for flexibility,
Tektronix has integrated complete digital
phosphor oscilloscope functionality into
the VM5000. Flexible and dedicated
video triggering for NTSC, PAL, SECAM
and analog HDTV is provided in the
oscilloscope. Optional application software
packages complement the standard
oscilloscope functionality to further extend
the return and value of a VM5000 platform
investment. Oscilloscope functionality
and specifications are detailed in the
TDS5104B or appropriate application
software data sheet(s).
