1730–Series Operating Instructions
2–5
14 INTENSITY
Controls display brightness.
15 ON
Switches between instrument in a powered up state and in standby. Portions of
the power supply circuit board still have mains potential on them. A mechanical
indicator in the center of the switch shows the status of the POWER switch.
WARNING. Power Supply Hazard:
Mains power is still applied to the 1730–Series power supply circuit board,
regardless of POWER switch state. To totally remove shock hazard it is
necessary to unplug the instrument and wait for capacitors to discharge.
16 ON
Toggles between ON and OFF. Line and field number are displayed on the CRT
in 1LINE or 2LINE sweep rates with a colon as a delimiter, for example: F1:19
(field 1, line 19). In LINE SELECT mode, the selected line is displayed in
1LINE sweep rate, the selected line is displayed first in the 2LINE sweep rate,
and a bright–up is provided to mark the selected line in 2FLD sweep rate. The
field from which the line will be displayed can be selected with the FIELD
switch.
15 LINE display is accessed by holding the LINE SELECT ON button until
there is recognition. In 2FLD, the 15 lines are intensified in the display. In 1 or
2LINE sweeps, the 15 lines are overlayed and the CRT readout is active, giving
the field and line of the first displayed line plus a small 15 immediately below
the colon in the readout.
Lines displayed in the LINE SELECT mode have their active video intensified
on the PIX MON OUT signal.
