Record Length
Record length refers to the number of data points that are stored to the acquisition memory for each channel.
Display record length refers to the data points from the data stored in the acquisition memory that are displayed
on the screen. Normally, the acquisition-memory record length and display record length are the same, but the
time axis setting may cause them to differ. When you change the time axis setting, the sample rate and record
length also change.
On the standard model of the DL850E/DL850EV, you can set the record length to a value between 1 kpoint and
250 Mpoint. Depending on the model, you can set the record length to a value of up to 2 Gpoint.
Acquisition Mode
Specify how the DL850E/DL850EV processes the sampled data, stores it in the acquisition memory, and uses it
to display waveforms. There are four acquisition modes: Normal, Envelope, Averaging, and BoxAverage.
Hard Disk Recording
When measurement starts, you can record data to an external hard disk that supports eSATA (external Serial
ATA; /HD0 option) or to an internal hard disk (/HD1 option).
You can load the saved data using the DL850E/DL850EV and convert it to a format that you can analyze on a
PC (ASCII or floating point).
* Models with the /HD0 option are equipped with eSATA connectors. You need to purchase a hard disk that
supports eSATA separately.
History
When waveforms are being measured, the waveform data stored in the acquisition memory as a result of a
trigger occurrence is displayed as a waveform on the DL850E/DL850EV screen and can be viewed. When
waveform acquisition is being triggered in succession and an abnormal waveform appears, it is impossible to
stop acquisition before a new waveform appears on the screen. Normally, it would be impossible to view the
abnormal waveform. However, with the history feature, you can view the past waveform data (history waveforms)
stored in the acquisition memory when waveform acquisition is stopped. You can select specific history
waveforms and display them.
You can also search through the history waveforms for waveforms that meet specified conditions.
• Zone Search
The DL850E/DL850EV searches for history waveforms that passed (or did not pass) through a specified
search zone.
• Waveform Parameter Search
The DL850E/DL850EV searches for waveforms whose measured waveform parameter values meet (or do
not meet) specified conditions.
Dual Capturing
You can use dual capturing to simultaneously record a trend at a low sampling speed in roll mode and at a high
sample rate. This is useful for capturing fast phenomenon while observing a trend over a long period of time.
