Input Gain Settings
Return to Introduction  Previous page  Next page
The input gain is adjusted by clicking on the Volts/Div rotary switch on each of the channel settings control panels shown below. Channels A and B have independent gain settings.

There are 9 gain settings available. Please note that if a gain setting is too high for the input signal, clipping will occur. To avoid clipping, select a larger voltage scale.

In addition, the settings depend on if the oscilloscope probe used is a x1 (1MW input impedance) or a x10 (10MW input impedance). If a x10 oscilloscope probe is used then enable the X10 setting by clicking on the X10 button located below the rotary switch. This will re-scale the switch and display cursor settings by a factor of 10.

In the picture above, the oscilloscope is setup for a x1 probe. The panel below shows the oscilloscope setup for a x10 probe.

The current gain setting is also displayed on the bottom right of the oscilloscope panel alongside the sampling rate. The presence of "X" indicates that the X10 button is active.
