This overload indicator may flash yellow briefly at start-up. This is not a cause for
concern.
3. SYNC OUT
. This connector supplies a SYNC output that can be used to trigger
other equipment, particularly oscilloscopes. This signal leads (or lags) the main
output by a duration set by the "DELAY" controls and has an approximate amplitude
of +3 Volts to R
L
> 1 kΩ with a pulse width of approximately 100 ns.
4. LIQUID CRYSTAL DISPLAY (LCD)
. This LCD is used in conjunction with the
keypad to change the instrument settings. Normally, the main menu is displayed,
which lists the key adjustable parameters and their current values. The
“Programming Manual for -B Instruments” describes the menus and submenus in
detail.
5. KEYPAD
.
Control Name
Function
MOVE
This moves the arrow pointer on the display.
CHANGE
This is used to enter the submenu, or to select the operating
mode, pointed to by the arrow pointer.
×10
If one of the adjustable numeric parameters is displayed, this
increases the setting by a factor of ten.
÷10
If one of the adjustable numeric parameters is displayed, this
decreases the setting by a factor of ten.
+/-
If one of the adjustable numeric parameters is displayed, and
this parameter can be both positive or negative, this changes
the sign of the parameter.
EXTRA FINE
This changes the step size of the ADJUST knob. In the extra-
fine mode, the step size is twenty times finer than in the normal
mode. This button switches between the two step sizes.
ADJUST
This large knob adjusts the value of any displayed numeric
adjustable values, such as frequency, pulse width, etc. The
adjust step size is set by the "EXTRA FINE" button.
When the main menu is displayed, this knob can be used to
move the arrow pointer.
6. DUT Door
. This is the door that provides access to the daughterboard ZIF socket.
To open it, pull on the chrome knob. When closed, the door is held latched in place
magnetically.
The high voltage output is automatically disabled when the DUT door is opened.
The door must be closed during tests.
7. HV PULSE CONNECTOR
. The BNC connector provides access to the high voltage
(±1.5 kV) pulse that is applied to the DUT, for monitoring purposes. This signal must
