the amplitude value with a digit blinking along with the amplitude
units. The new amplitude value will be entered here.
Note: The displayed amplitude is in volts peak to peak in to a
50Ω load with an amplitude range of 1.00mV to 10.0 Volts for the
models with frequencies of 20 MHz or less (1.00mV to 3.00V for the
model B8040FD)
The lower portion of the LCD displays the currently selected
waveform, along with its frequency and amplitude value.
Pressing the ◄" & "► button to the right will cause the digit
to the right to blink. To change this digit rotate the Encoder knob
clockwise to increment the digit or rotate the Encoder know
counter clock wise to decrement it.
Pressing the ◄" & "► to the left will cause the digit to the
left to blink and can be changed using the procedure in the
above paragraph
Pressing the ◄" & "► to the Amplitude position will cause
the currently selected amplitude units to blink. The amplitude
units are millivolts and volts. Rotating the Encoder knob
clockwise while the amplitude unit is blinking will cause the
amplitude to increase by a factor of 10. Rotating the Encoder
knob counter clockwise will decrease the amplitude by a factor
of 10.
Example: If the currently selected amplitude is 100 mV and
the mV unit is blinking, rotating the encoder clockwise 1 step will
increase the amplitude by a factor of 10 to 1.00 volts. Rotating
the Encoder knob counter clockwise 1 step will decrease the
amplitude by a factor of 10 to 10.0mV.
The keyboard can also be used to enter an amplitude value.
Entering a digit from the keyboard will clear the current value
and all digits being entered will blink, and then press the Enter
button. If the value entered from the keyboard is wrong and the
