View Parameters
View Parameters determine how the collected data are displayed and analyzed.
Scan Time (T)
There are 22 options for Scan Time (T). They are 100 µs, 200 µs, 500 µs, 1 ms, 2 ms, 5 ms, 10 ms, 20 ms, 50 ms, 100 ms, 200 ms, 500 ms, 1 s, 2 s, 5 s, 10 s, 20 s, 50 s, 100 s, 200 s, 500 s, Record.
This parameter is applicable to all types of views in the Oscilloscope.
Note that if you select longer scan time, it will take longer time for the acquired data and analyzed results to be shown on the screen.
If “Record” is chosen, the oscilloscope will enter into Recording Mode. Under this mode, raw ADC data will be written into the hard disk continuously in WAV file format. Meanwhile, data analysis and display will still be performed in order to keep the screen updated in real time. The scan time under this mode is fixed at 100 ms. The recording process can be stopped manually by pressing the Run/Stop button in the Instrument Toolbar. It will be automatically stopped if 2 gigabytes of data have been recorded. Only Auto Trigger Mode and Normal Trigger Mode are allowed under this mode. Sampling parameters are prevented from being changed during the recording process by the software. Upon finishing recording, the recorded file named “Record1.wav” will be opened automatically by the software. It may take quite long if the file is big.
Scan Time Multiplier
The Scan Time Multiplier is the zooming factor for T axis. There are 10 options available: ×1, ×2, ×5, ×10, ×20, ×50, ×100, ×200, ×500, ×1000.
When "×1" is selected, the full range of the Scan Time is displayed over the width of the view.
If you change the Scan Time Multiplier to "×N" which is greater than 1, then only 1/N of the full range of the Scan Time is displayed over the width of the view, with a horizontal scrollbar at the bottom which allows you to scroll over the full range of the Scan Time.
This parameter is applicable to all types of views in the Oscilloscope except Lissajous Pattern display.
Channel A Display Range
You can specify the Display Range for Channel A. Available options are: Off, ±100 µV, ±200 µV, ±500 µV, ±1 mV, ±2 mV, ±5 mV, ±10 mV, ±20 mV, ±50 mV, ±100 mV, ±200 mV, ±500 mV, ±1 V, ±2 V, ±5 V, ±10 V, ±20 V, ±50 V.
When "Off" is selected, the signal in Channel A will not be displayed in the Oscilloscope.
This parameter is applicable to all types of views in the Oscilloscope. It should be noted that in "Channel A + Channel B" view, this voltage display range is for "Channel A + Channel B". Similarly, In "Channel A – Channel B" view, it is for "Channel A – Channel B".
Channel A Multiplier
The Multiplier for Channel A is the zooming factor for A axis. There are 5 options available: Off, ×1, ×2, ×5, ×10.
When "Off" is selected, the full Display Range for Channel A is displayed over the height of the view.
When "×1" is selected, initially the full range is displayed over the height of the view with a vertical scroll bar on the left of the view. You can use the scroll bar to move the data curve for Channel A up and down.
If you change the multiplier to "×N" which is greater than 1, then only 1/N of the full range is displayed over the height of the view, with a vertical scrollbar on the left of the view. You can use the scroll bar to scroll over the full Display Range.
This parameter is applicable to all types of views in the Oscilloscope except Lissajous Pattern display. It should be noted that in "Channel A + Channel B" view, this parameter is for "Channel A + Channel B". Similarly, In "Channel A – Channel B" view, it is for "Channel A – Channel B".
View Type
There are four types of views in the Oscilloscope:
- &: Waveform display of Channel A and Channel B
- +: Waveform display of Channel A + Channel B
- -: Waveform display of Channel A - Channel B
- |: Lissajous Pattern display for Channel A and Channel B.
You can select one of them for display. The following figure illustrates the Lissajous Pattern of a 1 kHz sine wave in Channel A and 4 kHz sine wave in Channel B.
Channel B Display Range
You can specify the Display Range for Channel B. Available options are: Off, ±100 µV, ±200 µV, ±500 µV, ±1 mV, ±2 mV, ±5 mV, ±10 mV, ±20 mV, ±50 mV, ±100 mV, ±200 mV, ±500 mV, ±1 V, ±2 V, ±5 V, ±10 V, ±20 V, ±50 V.
When "Off" is selected, the signal in Channel B will not be displayed in the Oscilloscope.
For single channel data, this control will be disabled.
This parameter is only applicable to two types of views: Channel A & Channel B and Lissajous Pattern. It is disabled in the other two types of views.
Channel B Multiplier
The Multiplier for Channel B is the zooming factor for B axis. There are 5 options available: Off, ×1, ×2, ×5, ×10.
When "Off" is selected, the full Display Range for Channel B is displayed over the height of the View.
When "×1" is selected, initially the full range is displayed over the height of the view with a vertical scroll bar on the right of the view. You can use the scroll bar to move the data curve for Channel B up and down.
If you change the multiplier to "×N" which is greater than 1, then only 1/N of the full range is displayed over the height of the view, with a vertical scrollbar on the right of the view. You can use the scroll bar to scroll over the full Display Range.
This parameter is only applicable to one types of view: Channel A & Channel B. It is disabled in other types of views.
