Horizontal System ❙❙ Acquisition peak detection: Each A/D converter converts at the full sampling rate (no Interlace mode), even if results have not been written to the acquisition memory at full sampling rate (for slow time bases, for instance). If peak detection is activated, unused converter values will be evaluated to detect minimum and maximum amplitudes. During this process, the identified minimum and maximum values including sampling interval are written to the acquisition memory.
Horizontal System Fig.5.3: AM modulated signal with maximum sampling rate mum amount of data. Each column in the signal window displays up to 40 detected data values (limited by processor performance). How much data is currently displayed depends on the displayed time window and the current sampling rate. If peak detection is activated, each column displays up to 20 pairs of min/max values. The memory depth always corresponds to the maximum acquisition memory.
Horizontal System time bases. If a high repeat rate can only be attained by means of low memory depth (as is the case with other manufacturers) it is nearly impossible to zoom in retrospectively in STOP mode. 5.4 Interlace Mode In interlace mode, ADC and storage of two channels are connected. This doubles the sampling rate and the acquisition memory. Interlace groups are channels 1 and 2 and channels 3 and 4.

Basic display settings can be defined by pressing the DISPLAY 14 key in the GENERAL section.
Signal Display 7.3 Signal intensity and persistence functions Fig. 7.2: Menu for setting the signal display intensities The default setting (indicated as active when the INTENS/ PERSIST 7 key is illuminated in white) allows you to use the universal knob to change the intensity of the signal display to anywhere from 0% to 100%. Persistence mode allows the display of varying signals by enabling the instrument to write several signals on the display simultaneously.
Signal Display log channels can be selected as source. It is possible to define two signals as Y input and display vs. x input to perform a comparison. Press the soft menu key Z SETTINGS to determine the settings for the Z input. The function SOURCE Z allows you to use any of the analog channels as source for the Z input. Use the universal knob in the CURSOR/MENU section to select the desired setting. The Z input allows you to control the brightness of the XY signal.
Measurements PEAK VALUES: This mode provides two cursors to measure the minimum and the maximum voltage of a signal within the interval set by using both cursors. The values Vp- and Vp+ correspond to the minimum and the maximum voltage. The peak value (Vpp) corresponds to the amount of voltage between the minimum and maximum value.
Measurements RMS VALUE: This mode identifies the effective value from the displayed view of the signal. If the signal is periodic, the first period on the left of the screen will be used for the measurement. The effective value is not applied to a sine signal will be calculated directly (so-called TrueRMS). The measurement will only be applied to the selected channel.
Measurements σ-STD. DEVIATION: This mode measures the standard deviation of the signal amplitude in the displayed view of the screen. The standard deviation is the measurement for the deviation of a signal from its mean value. A low result indicates that the values are close to the mean value. A higher result illustrates that on average the difference between the values is greater. DELAY: This mode measures the time delay between the set measurement source and the reference source.
Measurements available for up to 1,000 captures. You can define the desired number with the universal knob or the KEYPAD key in the CURSOR/MENU section. The mean value and the standard deviation are identified by means of the most current n values where n corresponds to the set captures (soft menu key NO. OF AVERAGES). Minimum and maximum of the measurement value applies to the total number of measurements. The total number of measurements will be displayed in the statistics.

Addition (ADD) Multiplication (MUL) Subtraction (SUB) Division (DIV) You can use the universal knob in the Cursor/ Menu section to select operands and operators. Fig. 9.2: Quick mathematics menu 9.1.
Analysis For each corresponding equation, the input channels CH1, CH2, CH3, CH4 and an adjustable constant are allowed as OPERAND (sources). For the formula MA2, MA1 is added as source, for MA3 the added source is MA2, for MA4 it is MA3 and finally for MA5 the added source is MA4. From these five equations, you can create, save and retrieve a total of five different sets. New equations can be added by using the universal knob to select the menu item NEW in the formula set editor.
Analysis Afterwards, a new equation MA2 will be entered and adjusted. The result of the equation calculation „CURRENT“ and channel CH2 will be multiplied which will be yielded to a power curve. The equation MA2 can be named „POWER“ using the soft menu key LABEL. At last, a 3rd equation MA3 will be added to the set of formulas which will be defined as the integral of the equation „POWER“. The equation MA3 can be named „ENERGY“ using the soft menu key LABEL.
Analysis multiplied and the impact is damped. The soft menu item WINDOW allows you to choose from the following window functions: Hanning: The Hanning window function is bell-shaped. In contrast to the Hamming window function, it is equal to zero at the margin of the measurement interval. Therefore the noise level is reduced in the spectrum and the width of the spectral lines is increased. This function is useful for a precise amplitude measurement of a period signal, for instance.
Analysis the key COPY CHANNEL to copy the current signal into a mask memory. The mask displays in white and appears as an overlay of the output signal. The menu keys Y-POSITION and STRETCH Y enable you to shift this curve vertically or to enlarge it. The two menu items WIDTH Y and WIDTH X allow you to set the tolerance for the mask. The universal knob or the KEYPAD button in the CURSOR/MENU section are used to enter values with a resolution of 1/100 division.
