6. Entry keys

Keys used to enter numeric data into the E4980A/AL. The entry keys comprise
the digits 0 to 9, a period (.), and a plus/minus (+/-) sign. Entered values are
displayed on the input line (second line from the bottom of the LCD screen),
and pressing the softkey terminates numeric input. The plus/minus key deletes
the last character of the input value.

7. LED indicator

The LED indicator lights up when DC Bias or DC Source is on. The USB
indicator lights up while accessing a USB memory.

8. Preset key

9. Trigger key

A key used to manually trigger the E4980A/AL when it is set to the manual

10. DC Bias key

A key used to toggle on and off of the DC bias output. When the DC bias
output is set to on, the DC bias indicator lights up and DCBIAS is displayed in
the status display area on the screen.

to the LCD display, the DC bias is not output.
Regardless of which page is displayed, when the DC BIAS key is pressed,

DISPLAY) is output. For example, in case that DC Bias sweep has been set
