Computation
Item
Specifications
User-defined functions
Used to compute equations that are created by combining measurement function symbols and
operators (up to eight equations can be created).
Average active power setting Is set with a user-defined function.
Efficiency equation setting
Computes equations that are created by combining measurement function symbols (up to two
equations can be created).
Equation for apparent power
and reactive power
Can be set to Type 1, Type 2, or Type 3. Type 3 can only be selected on models with the harmonic
measurement option.
Phase difference display
Can be set to display the phase difference using a 180° lead and lag format or a 360° format.
Delta computation
Computes measured circuit values using the computed results of the differences of instantaneous
values. This feature can only be used on models with the delta computation option.
Distortion factor equation
The denominator of the equation can be set to the total waveform or to the fundamental signal. This
feature can only be used on models with the harmonic measurement option.
Numeric Display

Display format
Peak-to-peak compressed data
Sample rate
Approx. 100 kS/s
Waveforms can be reproduced accurately up to approximately 5 kHz.
Time axis
In the range of 1 to 500 ms/div. Must be less than or equal to 1/10 of the data update rate.
Trigger
• Trigger type:
Edge
• Trigger modes:
Auto and normal. Triggering is automatically switched off during integration.
• Trigger source:
Can be set to an external clock signal or to a voltage or current applied to an input element.
• Trigger slope:
(rising), (falling), or
(rising and falling).
• Trigger level
• When the trigger source is a voltage or current applied to the input element
The trigger level can be set in the range of ±100% from the screen center (to the top or
bottom edge of the screen) in 0.1% steps.
• When the trigger source is Ext Clk (external clock)
The trigger level is the TTL level. For the external clock specifications, see section 14.7.
Vertical waveform zoom
Each voltage or current waveform can be vertically scaled within the range of 0.1 to 100 times
magnification.
Turning waveform displays
on and off
The displays of each voltage or current waveform can be turned on or off.
Waveform display format
The split-screen options are: 1, 2, 3, and 4.
Waveform display
interpolation
The interpolation options are dot and linear.
Graticule
The graticule options are grid and cross-hair.
Turning auxiliary displays on
and off
The displays of the upper and lower limits (scale values) and of waveform labels can be turned on
and off.
Cursor measurement
A cursor can be placed on a waveform, and the values at the cursor location can be measured.
