Page 15: Introduction
With the exception of the instrument's power switch, all control is through the software-based graphical user interface. When used with a BERTScope Analyzer, the interface is found in “DPP Control,” listed in the top- level ‘Views’ menu. The DPP125 can also be operated standalone, using the BERTScopePC Standalone software supplied with the product and available at www.bertscope.com. -

Page 17: Installation
The DPP125 is intended to be operated in a controlled laboratory environment. It is intended to operate on a bench top, or on top of another instrument such as the BERTScope Bit Error Ratio Analyzer. There are four shock-absorbing feet located on the bottom of the instrument. Operate the instrument only when positioned with the feet facing downward. -

Page 19: Clock / Data Input Skew
Subrate Out to the DPP125 should be approximately 1.6 meters (62 inches) longer than the cable connecting the BERTScope Data Out to the DPP125 Data Input. With the additional cable length providing the rough delay match, use the calibration method described below to fine tune the delay match. - Page 20 Configuration 9. Run the Detector to check for error free operation. If not operating error free, advance the Generator delay by another ½ UI. The Detector should be operating error free at this point. Record the Generator Delay. 10. Once error free operation is obtained, find the boundary between error free and errored operation by decreasing the Generator Delay and using a binary search method as shown in Figure 3 below.

® The first time the BERTScope Analyzer starts with the DPP125 attached, the standard Microsoft Windows ‘New Hardware Found’ message will appear as the driver automatically loads. Select ‘DPP Control’ in the Analyzer’s ‘View’ menu to open the interface, a single view providing a complete control interface with the instrument. - Page 22 BERTScope.

Page 23: Use With Other Instruments
. 64-bit versions are not supported. Control communication is through USB 2.0 connection to the host computer rather than to a BERTScope Analyzer. The software should be installed in the host PC prior to connecting the USB cable. BERTScopePC software is distributed on a CD-ROM, which is supplied as a standard accessory with the DPP125. -
Page 24: Maintenance
The DATA IN and DATA OUT connectors use 3.5 mm to APC Planar Crown adapters. These facilitate user replacement of the adapter, should it become damaged. Replacement adapters can be ordered from Tektronix. The adapter is secured to the connector with a captive threaded mounting ring. Remove a damaged connector by grasping the knurled outer portion of the ring with your fingers and turning counter-clockwise. -
