Page 82 Math Waveforms Nyquist Frequency and Aliasing in the Frequency Domain NOTE The Nyquist frequency is the highest frequency that any real-time digitizing oscilloscope can acquire without aliasing. This frequency is half of the sample rate. Frequencies above the Nyquist frequency will be under sampled, which causes aliasing. The Nyquist frequency is also called the folding frequency because aliased frequency components fold back from that frequency when viewing the frequency domain.
Page 83: Fft Spectral Leakage
Math Waveforms Because the frequency span goes from ≈ 0 to the Nyquist frequency, the best way to prevent aliasing is to make sure that the frequency span is greater than the frequencies of significant energy present in the input signal. FFT Spectral Leakage The FFT operation assumes that the time record repeats.

Digital channel signal fidelity: Probe impedance and grounding When using the mixed-signal oscilloscope you may encounter problems that are related to probing.
Page 102 Digital Channels Passive probe input impedance is generally specified in terms of a parallel capacitance and resistance. The resistance is the sum of the tip resistor value and the input resistance of the test instrument (see the following figure). The capacitance is the series combination of the tip compensating capacitor and the cable, plus instrument capacitance in parallel with the stray tip capacitance to ground.
Page 103: Probe Grounding
Digital Channels The impedance plots for the two models are shown in these figures. By comparing the two plots, you can see that both the series tip resistor and the cable's characteristic impedance extend the input impedance significantly. The stray tip capacitance, which is generally small (1 pF), sets the final break point on the impedance chart.
Page 104 Digital Channels V = L di dt Increasing the ground inductance (L), increasing the current (di) or decreasing the transition time (dt), will all result in increasing the voltage (V). When this voltage exceeds the threshold voltage defined in the oscilloscope, a false data measurement will occur.

Either edge mode is useful when you want to trigger on any activity of a selected source. All modes operate up to the bandwidth of the oscilloscope except Either edge mode, which has a limitation.
Page 130: Pattern Trigger
Triggers Pattern Trigger The Pattern trigger identifies a trigger condition by looking for a specified pattern. This pattern is a logical AND combination of the channels. Each channel can have a value of 0 (low), 1 (high), or don't care (X). A rising or falling edge can be specified for one channel included in the pattern.
Page 131 Triggers • 0 sets the pattern to zero (low) on the selected channel. A low is a voltage level that is less than the channel's trigger level or threshold level. • 1 sets the pattern to 1 (high) on the selected channel.

Trigger Mode/Coupling To select the Auto or Normal trigger mode When the oscilloscope is running, the trigger mode tells the oscilloscope what to do when triggers are not occurring. In the Auto trigger mode (the default setting), if the specified trigger conditions are not found, triggers are forced and acquisitions are made so that signal activity is displayed on the oscilloscope.
Page 149: To Select The Trigger Coupling
Trigger Mode/Coupling • Auto? (flashing) — the trigger condition is not found (after the pre-trigger buffer has filled), and forced triggers and acquisitions are occurring. • Auto (not flashing) — the trigger condition is found (or the pre-trigger buffer is being filled).
Page 150 Trigger Mode/Coupling 2 In the Trigger Mode and Coupling Menu, press the Coupling softkey; then, turn the Entry knob to select: • DC coupling — allows DC and AC signals into the trigger path. • AC coupling — places a 10 Hz high-pass filter in the trigger path removing any DC offset voltage from the trigger waveform.
Page 151: To Enable Or Disable Trigger Noise Rejection
Trigger Mode/Coupling To enable or disable trigger noise rejection Noise Rej adds additional hysteresis to the trigger circuitry. By increasing the trigger hysteresis band, you reduce the possibility of triggering on noise. However, this also decreases the trigger sensitivity so that a slightly larger signal is required to trigger the oscilloscope.
Page 152: To Set The Trigger Holdoff
Trigger Mode/Coupling To set the trigger holdoff Trigger holdoff sets the amount of time the oscilloscope waits after a trigger before re-arming the trigger circuitry. Use the holdoff to trigger on repetitive waveforms that have multiple edges (or other events) between waveform repetitions. You can also use holdoff to trigger on the first edge of a burst when you know the minimum time between bursts.

Running, Stopping, and Making Single Acquisitions (Run Control) There are two front panel keys for starting and stopping the oscilloscope's acquisition system: [Run/Stop] and [Single].
Page 156: Overview Of Sampling
Acquisition Control When you press [Single], the display is cleared, the trigger mode is temporarily set to Normal (to keep the oscilloscope from auto-triggering immediately), the trigger circuitry is armed, the [Single] key is illuminated, and the oscilloscope waits until a trigger condition occurs before it displays a waveform. When the oscilloscope triggers, the single acquisition is displayed and the oscilloscope is stopped (the [Run/Stop] key is illuminated in red).
Page 157: Sampling Theory
Acquisition Control Sampling Theory The Nyquist sampling theorem states that for a limited bandwidth (band-limited) signal with maximum frequency f , the equally spaced sampling frequency f must be greater than twice the maximum frequency f , in order to have the signal be uniquely reconstructed without aliasing.
Page 158 Acquisition Control At the oscilloscope bandwidth, sampling theory says the required sample rate is f = 2f . However, the theory assumes there are no frequency components above in this case) and it requires a system with an ideal brick-wall frequency response.

Acquisition Control -3dB Aliased frequency components Frequency Limiting oscilloscope bandwidth (f ) to 1/4 the sample rate (f reduces frequency components above the Nyquist frequency (f Figure 23 Sample Rate and Oscilloscope Band width So, in practice, an oscilloscope's sample rate should be four or more times its bandwidth: f = 4f .
Page 160: Oscilloscope Bandwidth Required
Acquisition Control Oscilloscope Bandwidth Required The oscilloscope bandwidth required to accurately measure a signal is primarily determined by the signal's rise time, not the signal's frequency. You can use these steps to calculate the oscilloscope bandwidth required: 1 Determine the fastest edge speeds. You can usually obtain rise time information from published specifications for devices used in your designs.
