Period is defined as the time between the middle threshold crossings of two consecutive, like-polarity edges. A middle threshold crossing must also travel through the lower and upper threshold levels which eliminates runt pulses.
The X cursors show what portion of the waveform is being measured. Page Making Measurements threshold levels which eliminates runt pulses. The Y cursor shows the middle threshold point. Fall Time The fall time of a signal is the time difference between the crossing of the upper threshold and the crossing of the lower threshold for a negative-going edge.
For periodic signals, the position of the maximum may vary throughout the waveform. Page Making Measurements waveforms. Press the Settings softkey to select the source channels and slope for the delay measurement. Page Making Measurements Phase Phase is the calculated phase shift from source 1 to source 2, expressed in degrees.
Negative phase shift values indicate that the rising edge of source 1 occurred after the rising edge of source 2. Page Making Measurements Digital channel voltage measurements Automatic voltage measurements are not valid on digital channels on the mixed-signal oscilloscope.
Amplitude The Amplitude of a waveform is the difference between its Top and Base values. The Y cursors show the values being measured. RMS DC is the root-mean-square value of the waveform over one or more full periods. Page Making Measurements mean 1s 2s Page Making Measurements The Top of a waveform is the mode most common value of the upper part of the waveform, or if the mode is not well defined, the top is the same as Maximum.
The Y cursor shows the value being measured. To isolate a pulse for Top measurement The following figure shows how to use delayed sweep to isolate a pulse for a Top Page Overshoot And Preshoot Measurements Making Measurements Overshoot and Preshoot Measurements Digital channel time measurements Automatic measurements Preshoot and Overshoot are not valid measurements for the math FFT function or for digital channels on the mixed-signal oscilloscope.
Preshoot Preshoot is distortion that precedes a major edge transition expressed as a percentage of Amplitude. Page Making Measurements Overshoot Overshoot is distortion that follows a major edge transition expressed as a percentage of Amplitude. The X cursors show which edge is being measured edge closest to the trigger reference point. Page Pan And Zoom Displaying Data Pan and Zoom The ability to pan move horizontally and zoom expand or compress horizontally an acquired waveform is important because of the additional insight it can reveal about the captured waveform.
This additional insight is often gained from seeing the waveform at different levels of abstraction. Page Antialiasing Displaying Data Antialiasing At slower sweep speeds, the sample rate is reduced and a proprietary display algorithm is used to minimize the likelihood of aliasing. By default, Antialiasing is enabled.
You should leave Antialiasing enabled unless there is a specific reason to switch it off. Page Grid Intensity Displaying Data Accumulating multiple acquisitions Turning off infinite persistence does not clear the display. This allows you to accumulate multiple acquisitions, stop acquisitions, and then compare future acquisitions to the stored waveforms.
Clearing stored infinite persistence waveforms In addition to clearing the display by pressing the Clear Display softkey, the display is also cleared of previous acquisitions if you press the AutoScale key. Page Varying The Intensity To View Signal Detail Displaying Data Using Vectors Display menu One of the most fundamental choices you must make about your display is whether to draw vectors connect the dots between the samples, or simply let the samples fill in the waveform.
To some degree, this is a matter of personal preference, but it also depends on the waveform. High Resolution mode can be used on both single-shot and repetitive signals and it does not slow waveform update because the computation is done in the MegaZoom custom ASIC. Page Realtime Sampling Option Displaying Data Figure 46 Averages used to reduce random noise Realtime Sampling Option Realtime sampling specifies that the oscilloscope produce the waveform display from samples collected during one trigger event that is, one acquisition.
Use Realtime sampling to capture infrequent triggers, unstable triggers, or complex changing waveforms, such as eye diagrams. In this case, the reconstruction filter is not used. Realtime Sampling and Oscilloscope Bandwidth To accurately reproduce a sampled waveform, the sample rate should be at least four times the highest frequency component of the waveform. For I C triggering setup see page For SPI triggering setup see page Page Displaying Data b Press the Clock softkey, and use the Entry knob to select the channel probing the clock signal.
Page Displaying Data You can use the Delayed horizontal sweep mode for easier navigation of the acquired data. Page Displaying Data bus is measured. One Bit Sample Point 8 Set the trigger level. Frames of 11 or 29 bits are automatically detected. Scroll or expand the horizontal scale to view the information.
The totalizer is always running counting frames and calculating percentages and is displayed whenever CAN decode is displayed. Display Decode Signal Show Return to decode mode setup menu If a parity error is detected the hexadecimal ID and parity bits if enabled appear in red. The totalizer is running, counting frames and calculating percentages, even when the oscilloscope is stopped not acquiring data.
Page To Reduce The Random Noise On A Signal Displaying Data To reduce the random noise on a signal If the signal you are probing is noisy, you can set up the oscilloscope to reduce the noise on the displayed waveform. First, you stabilize the displayed waveform by removing the noise from the trigger path. LF reject removes low-frequency signals, such as power line noise, from the trigger path. Peak detect mode can be used to more easily view glitches or narrow pulses.
In peak detect mode, narrow glitches and sharp edges are displayed more brightly than when in Normal acquire mode, making them easier to see. Page How Autoscale Works Displaying Data How AutoScale Works AutoScale automatically configures the oscilloscope to best display the input signals by analyzing any waveforms present at each channel and at the external trigger input.
This includes the digital channels on MSO models. AutoScale finds, turns on, and scales any channel with a repetitive waveform that has a frequency of at least 50 Hz, a duty cycle greater than 0. Use the Print Config menu to choose the type of image file you would like to create or to set up your printer.
You can print scale factors, print in color or grayscale, and choose whether to print each waveform on a separate sheet of paper form feed. Maximum record length is obtained in single shot mode. Page Saving and Printing Data of the horizontal data points, and min and max values will be displayed on screen.
However, the oversampled data is also processed to provide a best-estimate value at each of the horizontal points. The data in the CSV file will be the best-estimate value at each of the horizontal points. You need a USB cable to connect the printer. Page Supported Printers Saving and Printing Data Supported printers Printers The following HP printers, available in stores at the time this manual was written, have been tested and found to be compatible with the Series oscilloscopes.

Page Digital Channel Signal Fidelity: Probe Impedance And Grounding Reference Digital channel signal fidelity: Probe impedance and grounding You may encounter problems when using the mixed-signal oscilloscope that are related to probing.
These problems fall into two categories: probe loading and probe grounding. Probe loading problems generally affect the circuit under test, while probe grounding problems affect the accuracy of the data to the measurement instrument. Page Reference 8. Page Reference Sharing one probe ground with many probes forces all the current that flows into each probe to return through the same common ground inductance of the probe whose ground return is used.
The result is increased current di in the above equation, and, depending on the transition time dt , the common mode voltage may increase to a level that causes false data generation.

A 3 dB increase represents roughly doubling the power, a 3 dB decrease, the power is reduced by about one half. Millimeter-wave Millimeter-wave is a term that generally refers to frequencies of That is where signal wavelengths fall below approximately 10 mm, and thus the terminology changes from centimeters to millimeters. Power Repeatability Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level.
Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account. Stability Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, remains fixed with the passage of time or with varying environmental conditions.
