Setting channel input parameters
Setting the probe attenuation factor
Attenuation is the amount that the probe reduces or ampli
fi
es 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
.

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
fi
eld 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
Ω
resistor 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.
