Measurement Functions display mode: Giving a better readability the display mode determines the rapidity of following up the input signal changes. The available modes are: • SLOW 3 seconds averaging • NRM 1 seconds averaging • FAST no averaging If averaging is active, measurements are smoothed in an exponential way (exponential time constant) before being displayed. 44
Level Sweep The Digilyzer supports a RMS based frequency sweep. This function can be applied to measure the frequency response of devices. During a frequency sweep, the Digilyzer records the Level RMS of every input signal, that has a stable frequency and level, provided that the frequency is higher than the one of the previous sample (otherwise the sample will be neglected). Arrow mode Zoom Y-Scale Measurement Functions Fig 5-43, Frequency sweep graph Within a graph every recorded sample is connected by a straight line approximately to the previous / next sample, thus building the displayed curve. In practice the following steps are required / available for the execution of a frequency sweep. • Arm the sweep recording process by moving the cursor to the REC field and pressing the enter key. • The DL1 detects the start tone (315 Hz or 1 kHz) of an external sweep and the recording is automatically started. This status is indicated by the flashing REC field. Alternatively, the sweep recording may be started manually by pressing the enter key with the cursor on the ARM field. Consequently, the DL1 records every incoming signal with a higher frequency than the previous sample. 45 Arrow readout
