Module compatib ility
between the TG8000 and
TG700 mainframes
Each of the modu
les that was designed to operate in the Tektronix TG700 TV
Signal Generator Platform will also operate in the TG8000 mainframe.
GPS7 module. The adjustment of the mainframe oscillator depends on the
mainframe in which the GPS7 module is installed:
TG8000 mainframe: You need to set only the internal frequency of the
mainframe oscillator. (See page 3-100, GPS7 module oven calibration
procedures.)
TG700 mainframe: You need to set the internal frequency of the mainframe
oscillator and characterize the mainframe oscillator frequency as a function o f
voltage. Refer to the TG700 User Manual for more information (Tektronix
part number 071-1970-XX).
GPS receiver: There are three versions of the GPS receiver as described
below. (See page 3-102, How to determine which GPS receiver is installed in
your GPS7 module.)
3002. This receiver supports GPS signals only and was replaced by the
3015 receiver. This receiver is compatible with both the TG8000 and
TG700.
3015. This receiver supports GPS and GLONASS signals and was
replaced by the 3023 receiver. T here are some reported limitations with
this receiver. See the TG8000 Release Notes for more information. The
TG8000 must have firmware version 1.6 or above installed and the TG700
must have firmware version 5.64 or above installed for this receiver to
operate.
NOTE. On the TG700, the GPS receiver module ID readout is not available.
Users need to view the GPS CONSTELLATION submenu of the GPS SETUP
menu to determine if the GPS/GLONASS receiver is installed.
3023. This receiver supports GPS and GLONASS signals. The TG8000
must have firmware version 2.5 or above installed and the TG700 must
have firmware version 5.64 or a bove installed for this receiver to operate.
SDI7 module. The behavior of the Moving Picture function depends on the
mainframe in which the SDI7 module is installed:
TG8000 mainframe: When Moving Picture is enabled, the circle and text
overlays remain static regardless of the signal type (standard test signal or
“frame (.BMP) picture”). However, the logo overlay remains static for only
standard test signals but continues to move when used with a “frame (.BMP)
picture.”
TG700 mainframe: When Moving Picture is enabled, the circle and text
overlays remain static and the logo overlay moves regardless of the signal
type (standard test signal or “frame (.BMP) picture”).
