Compensating the Oscilloscope Signal Path Signal path compensation optimizes the oscilloscope accuracy for the current ambient temperature. For maximum accuracy, recompen- sate the signal path if the ambient temperature changes by 5 C or more.
Page 37: Taking Floating Measurements
Functional Overview Taking Floating Measurements This section covers important issues to consider when taking floating measurements. Architecture is Important For taking floating measurements, the TekScope instrument has an architectural difference from most other oscilloscopes. The channel 1, channel 2, and DMM inputs are isolated from the main chassis and from each other.
Page 38 Functional Overview Many handheld oscilloscope/DMM products have the architecture shown below, which shares a common reference for the oscilloscope channels and DMM. With this architecture, all input signals must have the same voltage reference when you take any multi-channel measurements. Other product architecture Oscilloscope channels and DMM must float together.
Page 39 Functional Overview Attach the Reference Leads Correctly If you are using both of the oscilloscope channels, you must attach the probe reference lead for each channel directly to your circuit. These attachments are required because the oscilloscope channels are electrically isolated; they do not share a common chassis connection.

MEAS MEAS You can use the MEAS button to access the automatic measurement capability of the TekScope instrument. In scope mode, the instrument measures the 2500-point, selected waveform. In meter mode, the measurements take the form of statistics, which are calculated from successive meter readings.
Page 113 MEAS Key Points Choosing Measurements. You can perform up to four automatic measurements on the selected waveform and display them along the right side of the graticule. The table beginning on page 3–35 describes the scope-mode measurements in detail. Power Measurements (THS720P). Refer to page 3–20 for information about power measurements.
Page 114 MEAS High-Low Setup. The TekScope instrument determines the 10%, 50%, or 90% levels of the selected waveform and then uses them to calculate the measurements. You can choose the method used to determine these levels: Histogram sets the values statistically; it finds the most common value either above or below the midpoint (depending on whether it is defining the high or low reference level).
Page 115 MEAS Measurement Gating. You can use the gating feature to limit measurements to the portion of the waveform that is between the cursors. When you turn gating on, the instrument displays vertical bar cursors. Use the /– rocker and TOGGLE button to move the cursors to the area of interest.

Glossary and Index...
Page 216 Glossary /– Rocker The general-purpose rocker button on the front panel that you can use to set parameters. The specific parameter assigned to the /– rocker depends on other selections. AC Coupling A mode that blocks the DC component of a signal but passes the dynamic (AC) component of the signal.
Page 217 Glossary Attenuation The degree the amplitude of a signal is reduced when it passes through an attenuating device such as a probe or attenuator (the ratio of the input measure to the output measure). For example, a 10X probe attenuates, or reduces, the input voltage of a signal by a factor of 10.
Page 218 Glossary Common Lead The meter lead attached to the reference voltage in a measure- ment application. Because of the isolated channels, the meter common lead and the scope reference leads do not have to be connected to the same reference voltage. Continuity A test to verify electrical conductivity from one point to another.
Page 219 Glossary Diode Test A test to verify polarity and measure the forward voltage drop of a semiconductor junction. Displacement Power Factor (DPF) Cosine of the phase angle between fundamental components of the voltage and current waveforms. Display The word used to refer to the screen or the LCD (liquid crystal display).
Page 220 Glossary Ground (GND) Coupling Coupling option that disconnects the input signal from the vertical system. Hard Copy An electronic copy of the display in a format useable by a printer or plotter. Harmonics Voltage or current waveforms having frequencies that are integer multiples of the base (fundamental) frequency.
Page 221 Glossary Menu A set of labels shown in the display to identify the functions of the bezel buttons. The specific menu contents depend on the menu button you press. Motor Trigger Triggering on the rising or falling edge of a bipolar, motordrive waveform.
Page 222 Glossary Power Factor (PF) The ratio of true power (watts) to apparent power (volt- amperes). Pretrigger The specified portion of the waveform record that contains data acquired before the trigger event. Pulse Trigger Triggering on events that you can qualify by time. The oscilloscope triggers when an incoming pulse width meets time criteria you have defined.
Page 223 Glossary Roll Mode An acquisition mode useful at slow horizontal scale settings. Roll mode allows you to view the waveform as it is acquired point-by-point. The waveform appears to roll across the display. RS-232 The serial communication port used to connect to a hard-copy device, computer, controller, or terminal.
Page 224 Glossary Signal Path Compensation (SPC) The ability of the oscilloscope to minimize the electrical offsets in the vertical, horizontal, and trigger amplifiers caused by ambient temperature changes and component aging. You should run SPC when the ambient temperature varies more than 5 C from the last SPC or before performing critical measurements.
Page 225 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. Video Trigger Triggering on the sync pulse of a composite video signal.
