Tracer Test
Delay: Sampling delay time. This is the time from the beginning of the
pulse period to the beginning of the waveform sampling, -30 s
to pulse period.
Duration: Duration to sample the waveforms, 22 s to 24 ms.
Arithmetic Operation Area
This area appears at the top of the graph by clicking the Option > Arithmetic
Operation > Operation N (N: 1, 2, or 3) menu, and is used to define arithmetic
expressions using the measurement result data. This function is useful to graphically
display parameters given by the expressions.
Maximum of three expressions can be defined as Operation 1, Operation 2, and
Operation 3. An expression can be defined by two operands and an operator +
(addition), - (subtraction), * (multiplication), or / (division). The following
elements can be the operand.
• Measurement data (e.g. Imeas)
• Source data (e.g. Vset)
• Real literal constant (e.g. 2, 0.123, or 100E-3)
• Operation 1 result (e.g. Vdrop), for the expression of Operation 2 and/or
Operation 3
• Operation 2 result (e.g. Vout), for the expression of Operation 3
Example The following example calculates the voltage drop (Vdrop) caused by a 100 k
series resistor and measurement current (Imeas), then calculates the voltage
(Vout) applied to a device under test by subtracting the voltage drop from the
setting value (Vset).
Operation 1:
[ Vdrop ] = [ 100e3 ] * [ Imeas ]
Operation 2:
[ Vout ] = [ Vset ] - [ Vdrop ]
NOTE “NaN” is returned for the invalid calculation results.
NOTE To disable the operation, click the Option > Arithmetic Operation > Operation N
menu and uncheck the Operation N menu.
