Setting the probe attenuation factor
Attenuation is the amount that the probe reduces or amplifies the input signal amplitude before sending it to the oscilloscope
input. The Attenuation submenu sets the probe attenuation factor for probes that do not have the TekProbe II or TekVPI
interface. The default attenuation is 10x.
1. Push the Vertical Menu button for the
channel input that you want to set.
2. Push the Probe Setup side menu to display the Probe Setup submenu.
3. Use the Multipurpose knob to select and click the Attenuation submenu item.
4. Use the Multipurpose knob to select and change the attenuation factor.
Quickly s etting the probe attenuation to 1X or 10X
The Set To 1X and Set To 10X submenu items let you quickly set the probe attenuation to either 1X or 10X.
1. Push the Vertical Menu button for the
channel input that you want to set.
2. Push the Probe Setup side menu to display the Probe Setup submenu.
3. Use the Multipurpose knob to highlight either Set To 1X or Set To 10X submenu item. Then click the multipurpose
knob to set that value.
Setting the Measure Current mode for voltage probes
If you are measuring current by using a standard voltage probe to measure the voltage drop across a resistor, use the
Measure Current field to set the Amps/Volts or Volts/Amps ratio of your measurement setup. For example, if you are
measuring the voltage drop across a 2  r
esistor to determine the current, set the V/A ratio to 2.
1. Push the Vertical Menu button for the
channel input that you want to set.
2. Push the Probe Setup side menu to display the Probe Setup submenu.
