Resets the contents of NVRAM to factory defaults. This is especially necessary
when upgrading the instrument firmware. After setting NVRAM to defaults, it
returns to the main menu.
Operator’s Checkout Procedure
The following procedure is provided as an aid in obtaining a display on the
1735 HD Waveform Monitor. This procedure may be used for operator familiar-
ization and as a check of basic instrument operation. This procedure checks
instrument functions rather than measurements or specifications.
WARNING.
Be sure that the cabinet is installed on the instrument to avoid
personal injury. When power is supplied, line voltage will be present in the
instrument, even if the power switch is set to standby.
All checks are made with the cabinet installed to maintain the proper environ-
ment for the instrument, keep dust out and provide proper EMI shielding. All
internal jumpers are in their factory installed position.
If performing the Operator’s Checkout Procedure reveals improper operation or
instrument malfunction, first check the operation of the associated equipment. If
the associated equipment is operating normally but the 1735 HD is not, it should
be repaired or adjusted by qualified service personnel.
When a complete check of instrument performance is desired, refer qualified
service personnel to the Performance Verification procedure provided in this
manual.
The Operator’s Checkout Procedure requires a source of composite video. The
television signal generator must be capable of delivering a color bar test signal, a
five-step linearity signal, a multiburst signal and a sync signal for the television
standard of the monitor to be tested. A Tektronix TSG 1001 was used in this
procedure.
Be sure that the instrument is configured for the scanning standard used for this
procedure. See “Configuring Menus” (earlier in this section) for the procedure to
select the scanning standard.
1. Initial Hook-up
Connect the generator G/Y OUT to the 1735 HD CH 1A connector, as
shown in Figure 2–7. Terminate the loop-through in 75
W
.
2. Initial Generator Setup
Select the NTSC Format SMPTE Bars signal from the TSG 1001. The 5-step
linearity and multiburst signals will also be used later in this procedure. Note
that these are not full amplitude signals.
