Data Logging
The LogTxt macro can be used together with a timer macro in a loop to produce a data log that consists of a timed series of data samples. Each line in the file can be anything you want, typically a time-stamp (including date, if desired) plus one or more values recorded at that time. The interval between samples can typically be from less than a tenth of a second, up to hours or days... or even longer.

Event Detectors
105/106 Series
The 105/106 Series Event Detectors are the most versatile Event Detectors in the product line. These Event Detectors monitor the electrical resistance of up to 128 simple continuity loops, each comprised of single or multiple specimens under test. Each test specimen is continuously monitored while a selectable DC sense current is passed through each channel test-loop; resistance changes exceeding the selected threshold are recorded as an event. Minimum Event Duration, Channel Current, and Threshold Voltage settings can all be independently configured. 105 and 106 Series instruments are electrically identical, with the difference simply that the 105 offers four, 32-channel board slots and the 106 offers only one. Thus the 128-105 is equivalent to four 32-106 Event Detectors.

Power Conversion
The XRP6124 is a non synchronous step down (buck) controller for up to 5A point of loads. A wide 3V to 30V input voltage range allows for single supply operations from industry standard 3.3V, 5V, 12V and 24V power rails. With a proprietary Constant On-Time (COT) control scheme, the XRP6124 provides extremely fast line and load transient response while the operating frequency remains nearly constant. It requires no loop compensation hence simplifying circuit implementation and reducing overall component count. The XRP6124 also implements an emulated ESR circuitry allowing usage of ceramic output capacitors and insuring stable operations without the use of extra external components.

Telephone & Exchange Tester
ETT 10
Maintenance statistics of telephone networkshave shown that for most of the failures, theexchange - line - subscriber (EXCH-LINE-TEL) sections are responsible. Accordingly, the first step of the troubleshooting procedure is to locate the breakdown spot, i.e. to find out whether thefailure source is within the exchange, the subscriber site or in the line (local loop). Thisproblem can be easily solved by theTelephone & Exchange Tester ETT 10, in most cases without requiring the technician to visit the subscriber or the junction boxes along the line.

Compression Unit
BK1611
The BaKo BK1611 is a Compression Unit that uses a real time feedback loop to create a frequency sweep with constant level output. This would normally be used for either research or for calibration rather than product line testing and is useful because of its extreme stability. The BK1611 is not a dedicated system so it can be integrated into a variety of systems to be used for microphones, speakers or vibration motors.

Loop Resistance Measuring Device According to DIN EN 61557-3 (VDE 0413-3)
PeakTech Prüf- und Messtechnik GmbH
A loop tester which is used to test the safety of electrical systems. These device measures the impedance of the short-circuit loop between the outer conductors of a circuit, whereby the probable short-circuit current is calculated. The protection of the circuit (miniature circuit breaker) must therefore trigger at a lower current than the expected short-circuit current, in order to avoid excessive heating of the lines and thus a fire risk. The PeakTech 2715 is due to its function and its robust design almost indispensable when performing new installations, but also for general checking of electrical systems, this device is the ideal companion.
