Adjustment This section contains information you need to adjust the TDS 310, TDS 320, and TDS 350. There are only three types of adjustments you can perform on the oscilloscope: the automated and semiautomated adjustments in the system calibration menu, attenuator adjustments, and monitor adjustments.
Page 152: The System Calibration Menu
Adjustment The oscilloscope has four onboard calibration routines. You can access these The System routines through the system calibration menu. Use the following procedure. Calibration Menu NOTE Except for early TDS 320 oscilloscopes, the Voltage, Timing, and External Trigger calibration routines are disabled at the factory. To enable the calibration menus, see Enabling Calibration Menus, on page 8 29.

Page 227 This reduces the apparent noise. The oscilloscope acquires data as in the sample mode and then averages it according to a specified number of averages. TDS 310, TDS 320 & TDS 350 Instruction Manual www.valuetronics.com...
Page 228 Glossary Burst width A timing measurement of the duration of a burst. Cursors Paired markers that you can use to make measurements between two waveform locations. The oscilloscope displays the values (expressed in volts or time) of the position of the active cursor and the distance be tween the two cursors.
Page 229 Amplitude (voltage) measurement of the minimum amplitude. Typically the most negative peak voltage. Negative Duty Cycle A timing measurement representing the ratio of the negative pulse width to the signal period, expressed as a percentage. TDS 310, TDS 320 & TDS 350 Instruction Manual www.valuetronics.com...
Page 230 Glossary Negative Overshoot Measurement Amplitude (voltage) measurement. NegativeOvershoot + Low * Min 100% Amplitude Negative Width A timing measurement of the distance (time) between two amplitude points falling edge MidRef (default 50%) and rising edge MidRef (default 50%) on a negative pulse. Normal Trigger Mode A mode on which the oscilloscope does not acquire a waveform record unless a valid trigger event occurs.
Page 231 The set of parameters that let you define the time and horizontal axis attributes of a waveform record. The time base determines when and how long to acquire record points. TDS 310, TDS 320 & TDS 350 Instruction Manual www.valuetronics.com...
Page 232 Glossary Vertical Bar Cursors The two vertical bars you position to measure the time parameter of a waveform record. The oscilloscope displays the value of the active (moveable) cursor with respect to trigger and the time value between the bars. XY Format A display format that compares the voltage level of two waveform records point by point.
