Page 4: Operation
OPERATION Power on the unit • You can select from two power supply methods : internal battery power or external DC adaptor power. Power supply voltage of the DC adaptor is grid voltage. After connecting to power, start the self calibration process by pressing the [USER] button then [F3]. -
Page 5: Using The Autoset Function
Using the Autoset function • Connect the signal to be measured to the signal input channel. • Press AUTO and the oscilloscope will scan the time base and trigger mode and set the vertical deflection factor. You can manually adjust further after this process to get the optimum display. -
Page 6: Instrument Setup
INSTRUMENT SETUP Resetting the Instrument • To use factory setup, follow the steps below : • After connecting to power press [POWER] to turn the oscilloscope on. When the power-on screen appears, press and hold the [CLEAR/MENU] key to select factory setup. -
Page 7: Setting Channel Coupling
Others Probe ratio Select one of the values based on the probe attenuation factor to keep the reading of the 100X signal being measured correct. 1000X Polarity Normal Normal waveform display Invert Waveform is inverted Setting channel coupling • To apply a signal to Channel A. The signal being tested is a sine signal that contains DC quantities. - Page 8 Setting bias voltage • Bias voltage is suitable for observing the following signals: • The input signal is made up of relatively high DC quantities and relatively low AC quantities. • The input AC signal is very low in frequency and contains DC quantities. AC mode is unsuitable.
- Page 9 Trigger System Setup • Triggering decides when the oscilloscope collects data and display waveforms. Once the trigger is correctly set up, it can transform unstable displays into meaningful waveforms. • When beginning to acquire data, the digital storage oscilloscope first collects sufficient data required for drawing a waveform on the left side of the trigger point.

Page 10: Pulse Trigger
Pulse Trigger • When the pulse width of the trigger signal reaches a preset trigger condition, trigger occurs. • Pulse trigger means determining the triggering time based on the pulse width. You can acquire abnormal pulse by setting the pulse width condition. Function Setup Explanation... -
Page 11: Alternate Trigger
• When synchronization mode is “odd field”, you will see a screen display as shown. Alternate Trigger • When alternate trigger is selected, trigger signals will be present in their individual vertical channels. This triggering mode is suitable for observing two signals of uncorrelated signal frequencies. - Page 12 Pre-trigger/Delayed Trigger: Data sampled before/after triggering. The trigger position is typically set at the horizontal center of the screen. In this case, you are able to view 6 divisions of pre-trigger and delayed information. Adjusting the horizontal position of the waveform allows you to see more pre-trigger information.
- Page 13 Note A • Use Real time sampling to observe single signals. • Use Equivalent sampling to observe high frequency cyclical signals. • To avoid mixed envelop, select Peak Detect. • To reduce random noise of the displayed signal, select average sampling and increase the average number of times in multiples of 2, i.e selecting from 2 to 256.
- Page 14 OPERATION To display the measurement peak-to-peak value of Channel A • Press [A] to turn on Channel A. • Press [SCOPE] to enter the frequently used function menu. • Press [F2] to enter the parameter measurement options. • Press [F1] to select customized parameter for parameter measurement.
- Page 15 To display all measurement values of Channel A • Press [A] to turn on Channel A. • Press [SCOPE] to enter the frequently used function menu. • Press [F2] to enter the parameter measurement options. • Press [F1] to select customized parameter for parameter measurement.
- Page 16 To request recalling a recorded waveform document saved on the USB device • Insert the USB device and press [SAVE] to access the storage menu. Press [F3] to select the recording function. • Press [F3] to select “import”, then press [F2] to activate the “USB document”...
- Page 17 Cursor Measurement • Press [CURSOR] to display the cursor measurement menu, and then press [F1] to activate the cursor. • The [CURSOR] menu offers two cursor measurement modes: voltage and time. • When measuring voltage, press [F2] on the front panel and the jog dial to adjust the positions of the two cursors for ΔV measurement.
- Page 18 Operating Math Functions • Math functions are displays of +, -, ×, ÷ and FFT mathematical results of Channel A and Channel B. • Press [MATH] then [F1] to select FFT, +, -, ×, ÷ or OFF as the math type. Functions Menu Setup Notes...
- Page 19 whole number, there will be different amplitudes at the start and finish, resulting in transient interruption of high frequency at the connection point. In frequency domain, this is known as leakage. To avoid leakage, multiply the original waveform by one window function to set the value at 0 for start and finish compulsively. For application of the window function, please see the table below : Feature Most suitable measurement item...

Page 20: Auto Setup
Using the Run button • There is a [RUN/STOP] button on the front panel. When this button is pressed your oscilloscope stops acquiring data. To restart data acquisition, press it again. Auto Setup: • Auto Setup can simplify operation. • Press [AUTO] and the oscilloscope can automatically adjust the vertical deflection factor and horizontal time base range according to the amplitude and frequency of the waveform, so as to ensure stable waveform display. -

SYSTEM PROMPTS Definitions of System Prompts Adjustment at Ultimate Limit: This informs you that the multifunction control knob has reached its adjustment limit in the current status. No further adjust is possible. When the vertical deflection factor switch, time base switch, X shift, vertical shift and trigger level adjustments have reached their ultimate limits, this prompt will appear. - Page 22 Tenma and UniTrend. • You have to own a compatible oscilloscope manufactured by Tenma. To check the model, hardware version and software version of the unit, go to the system information sub-menu under the user menu.
