Functions
Long Memory and Easy Zoom Function
Accurately Capture and Observe Waveforms with the 8 Mword Long Memory and Easy Zoom Function
Even some oscilloscopes with high sampling rates may not be able to accurately capture waveforms if the memory size is not large enough for the required monitoring period. This limitation is due to the necessary drop in sampling rate, which occurs if the recording memory is not long enough. A larger recording memory not only increases the monitoring time, but also enables users to maintain a high sampling rate thus ensuring accurate waveform representation. In addition, the zoom function can be used to simultaneously view enlarged images on one or two segments of a waveform captured in the large memory.

All-Points Display and Fast Screen Updates
All-Points Display and Fast Screen Updates Make Sure You Won't Miss Abnormal Signals
When working with data captured in the large recording memory, the amount of information appearing on the display varies greatly depending on how the data are presented. The differences occur depending on whether you choose to display all points in a captured waveform, or just major values, such as maximum and minimum values, in a given segment on the waveform. The DL1700E Series provides fast screen updating in all-points display mode, so you won't miss abnormal phenomena or have slow responses to instrument controls.

Smart Search Function
Smart Search Function for Effective Access to the Data You Need
"I want to find the serial data with a particular serial pattern", "I need to search for surge pulses of less than 30 ns", "I want to only extract waveforms that occasionally overshoot by an excessive amount".......As data volumes increase, it becomes more important to be able to search for target phenomena efficiently. The Smart Search function automatically detects serial patterns, pulse widths, rising edges, falling edges, and other phenomena in the captured waveform data. These phenomena are then displayed in the zoom screen. Smart Search will significantly improve the efficiency of your development and evaluation work.

History Memory and History Search
When an abnormal signal is displayed on the screen, does it disappear before you can press the STOP key?
| History Memory The history memory function divides the large recording memory into a number of blocks and automatically saves up to 2048 previously captured waveforms. Increase the number of screens saved to history memory by setting a shorter record length. |
 |
| History Search The history search function is useful for quickly finding abnormal waveforms in the large amounts of waveform data stored in history memory. This function lets you automatically search for desired waveforms based on whether or not a signal passes through a user-defined area on the screen. You can also conduct searches based on waveform parameters. |
 |
| History Statistics Calculates statistical information based on the parameter values for waveforms stored in history memory. This function calculates and displays a parameter's maximum value, minimum value, average value, and standard deviation. You can check the parameters for every waveform in history memory. |

Measuring Periodically Fluctuating Amplitudes
 Cycle Statistics
|
Cycle Statistics Automatically calculates the maximum value, minimum value, average value, and standard deviation of selected waveform parameters for each period of a signal. You can even find the period corresponding to the calculated maximum and minimum values and display that period in the zoom window. In some applications, like with a PWM (pulse width modulation) control signal, you may need to determine information about each waveform period for long amounts of time. The DL1700E Series with its long memory, lets you analyze a long waveform, period-by-period, based on the period of a reference signal. |
How can I quickly count a large number of pulses in a waveform?
 Pulse count
|
Pulse Count Automatically counts the number of pulses in the waveform data between cursors. The threshold level for recognizing a single pulse is user-definable, so you can reliably compute pulses even in signals with unstable levels. With the DL1700E Series, you'll never again have to manually count pulses on screen or on a stack of printouts. |
Envelope and Roll modes
Envelope and Roll modes for simultaneously observing both slow and fast signals
Envelope mode always captures signals at the highest sampling rate, irrespective of the time-axis setting. This mode is effective when observing high-frequency noise superimposed on a slow signal. Roll mode allows you to observe signals on the screen in much the same way as you record them on a chart recorder. When in normal mode, you can set the sampling rate as high as 2 MS/s for roll mode. In addition, you can have a roll-mode view of signals in the envelope mode. |

Simple and Enhanced Triggers
Simple and Enhanced Triggers for Reliable Capturing of a Variety of Waveforms
Action-On Trigger
With the action-on trigger, a specified action is automatically executed each time the trigger is activated. You can use the trigger for a variety of actions, such as automatically saving captured data. The action-on trigger is useful for purposes such as collecting data in continuous rests.
GO/NO GO Judgment
GO/NO GO Judgment - Automatic Waveform Discrimination
 |
Select zones or paramenters for the waveform of an acquired signal. The DL1700E judges the signal being measured and automatically takes action. Actions you can choose from include: outputting screen images data to the destination specified in the Copy Setup menu, saving waveform data in the medium specified in the File menu, sounding the buzzer, and sending e-mail. |

Dedicated I²C Bus Trigger and Analysis Function
I²C bus signals (SCL and SDA) used extensively in home electronics such as televisions and video cameras and in communications equipment such as mobile phones can be captured with specialized triggers, analyzed, and displayed as waveforms.
| I²C Bus Analysis Function (Optional) Triggers can be activated using conditions such as Start, Non-Ack, Address pattern, and Data pattern. These dedicated I²C bus triggers can also be combined with other analog signals to activate additional triggers. |
 |
| I²C bus trigger setup menu | |
| I²C Bus Analysis Function (Optional) Captured waveforms can be analyzed in a time series manner, and the analysis results displayed in a list. When an analysis result is selected with the cursor, the corresponding waveform is automatically enlarged in the zoom area. Two pairs of I²C busses can be input at the same time, then analysis can be performed alternately on either bus. |

Dedicated SPI Bus Trigger and Analysis Function
The SPI data bus is a synchronous 8-bit serial bus used widely for inter-IC and data communications in embedded systems. SPI bus signals can be captured using the DL1700E dedicated triggers and the waveforems can be analyzed and displayed on the screen.
| SPI Bus Trigger Function (Optional) Triggers can be activated by comparing each byte of MOSI (master output slave input) and MISO (master input slave output) data with specified conditions. You can trigger on user-defined strings of data from 1 to 8 bytes long. SPI Bus Analysis Function (Optional) Data analysis results and SS (slave select) bits can be displayed in a list together with the waveforms. You can perform a high speed search for a specified MOSI or MISO data pattern (of 1 to 8 bytes) from within all of the captured data. |

Reviews
Panasonic AVC Networks Australia Pty. Ltd.
Mr. David Corkery, Production engineering manager,
Panasonic AVC Networks Australia Pty. Ltd.
My name is David Corkery and I am the Production Engineering Manager for Panasonic AVC Networks Australia. At our plant at Penrith we manufacture color televisions primarily for the local market and export some to New Zealand. The annual production for the past few years has been around 100,000 units.
All of the models use the IIC bus system and many of the adjustments can now be automatically done using a computer and a compatible oscilloscope. With this change in technology we began using Yokogawa scopes and now have approximately 18 varying from the DL1200 which was used in the early days to our latest purchase of the DL1740.
The main measurements modes we use are for DC voltage levels and some AC and RMS voltage checks. By using different channels and switching between them we can use the one scope and make several different adjustments. The programmes are developed by our engineers in the workshop prior to being installed into the production line.
By being able to automate some of the alignment stations we have been able to increase productivity and gain more consistent results compared with the original manual system. We have always found the scopes to be accurate and reliable which is important as our adjustment lines are now dependant upon their successful operation.
