If your DL series oscilloscope is not measuring rise or fall time, it may be because you are attempting to measure asymmetric waveforms. It is not possible to perform automatic rise or fall time measurements on DL series oscilloscopes when observing asymmetric waveforms. You will need to use a pair of cursors and manually set up the distal, mesial, and proximal reference levels.
This issue can be further explained as follows. When observing the falling portion of a waveform, with amplitude A, the FALL time will be measured. For the same waveform, observed on the rising portion, with an amplitude B where A>B or B>A, the RISE time will not calculate properly. This is caused by the fact that the max value was established when the FALL time was measured and is not reached when observing the RISE portion of the waveform. The two observed waveforms are asymmetric and have different max values.
Please see an example of this issue on the DL1600 in the attached screenshot. The rising step on CH1 is approximately 500V, with reference levels of:

Data acquisition (DAQ) is the measurement, recording, analyzing, and presentation of real world phenomena. It includes electrical measurements such as voltage, current, power as well as measurements through sensors and transducers including temperature, pressure, strain, vibration, and more.
Yokogawa high speed data acquisition systems deliver industry leading isolation, bit resolution, sampling rate, and memory depth, with independent channel hardware and easy to use software.
A mixed signal oscilloscope is an instrument enabling the simultaneous, time correlated observations and analysis of analog with digital (logic) signals, to establish causal relationships between the various areas of a device's electronics. They are purpose-built tools for troubleshooting electrical anomalies, measuring parametric values, and monitoring cause and effect relationships between signals.
Capture, analyze, and troubleshoot electrical or real-world physical signals. Oscilloscopes observe the change of electrical signals over time, continuously graphed on a display as voltage or amplitude vs. time.
A ScopeCorder is an instrument combining a mixed signal oscilloscope and portable data acquisition recorder into a modular platform designed to capture both high-speed transients and low-speed trends. Yokogawa’s ScopeCorder product family provides flexible and high-performance multi-channel test instruments by combining a variety of signal conditioning input modules, onboard calculations, and deep data acquisition storage into an off-the-shelf data acquisition solution.
