and ∫ dt when 1-2 or 1+2 is the selected source if channel 1 and
channel 2 are set to dissimilar units in the channel Probe Units

Math Measurements and Units
Only Peak-Peak, Maximum, Minimum, Average, X at Min, and X at Max automatic
measurements may be made on a math FFT function. See "Making time
measurements automatically" for the FFT X at Max and X at Min measurement.
Use the cursors to make other measurements on FFT. All voltage measurements
may be made on other math functions. The resultant units are:
FFT: dB* (decibels)
2 2
1 * 2: V , A or W (Volt-Amp)
1 – 2: V (Volts) or A (Amps)
d/dt: V/s or A/s (V/second A/second)
∫ dt:
Vs or As (V-seconds or A-seconds)
* When the FFT source is channel 1, 2, 3, or 4, FFT units will be displayed in dBV
when channel units is set to Volts and channel impedance is set to 1 M . FFT
units will be displayed in dBm when channel units is set to Volts and channel
impedance is set to 50 . FFT units will be displayed as dB for all other FFT
sources or when a source channel's units has been set to Amps.
The following figure shows the voltage measurement points.
