Adjusts the horizontal gain in the X line generator.
2 Adjusts the beginning of the trace to the leftmost
vertical graticule line in fast-analog, zero-span mode.
2 Adjusts the vertical gain in the Y line generator.
2 Adjusts the vertical position in fast-analog, zero-span
to match the digital zero-span input.
2 Adjusts the blanking at the end of a vector on
the display.
2 Adjusts the blanking at the start of a vector on
the display.
2 Adjusts the vertical gain in fast-analog, zero-span
to match with the digital zero-span input.
2 Adjusts the end of the trace to the rightmost
vertical-graticule line in fast-analog,
zero-span mode.
13 Adjusts the FM demodulation for a peak response.
Adjusts Limiter Phase for peak response
