Page 6: Operating The Counter
Chapter 3 Operating the Counter Introduction Getting Familiar with the Counter While this counter has a vast array of features and operating modes, the majority of the most useful functions can be learned The front panel is laid out in a logical fashion. Take a few seconds in just a few minutes. -
Page 7: Description Of Keys
Description of Keys Presentation Modes Power VALUE The ON/OFF key is a toggling secondary power switch. Part of the instrument is always on as soon as line power is applied, and this so-called standby condition is indicated by a red LED above the key. -

• Histogram Mode Filter: On or Off. Pressing ENTER or the soft key below the text opens up the Filter Settings menu. See below. You can select a fixed 100 kHz analog Successive measurement results are converted into a histogram. The number of bins along the horizontal axis can be set by the user through the Settings ->... -
Page 9: Math/Limit
Trigger Hold-Off Math In this menu you can set the delay during which the stop trigger conditions are ignored after the measurement start. A typical use is to clean up signals generated by bouncing relay contacts. Statistics You can modify the measurement result mathematically by scaling or offsetting before presentation on the display. -

About (Information) Read status information about the instrument. • Model • Serial number • Firmware version • Factory-installed options • Calibration date • Setup Protect: ON or OFF. Only setup positions 1-10 can be Hold/Run protected against inadvertent overwriting. This key serves the purpose of manual arming. A pending Calibration Menu measurement will be finished and the result will remain on the display until a new measurement is triggered by pressing... -
Page 11: Exercises
Chapter 4 Exercises Preparation For these exercises you will need a ‘9X’ counter, a function generator and two BNC cables of approximately equal length. Set up the generator according to the following table, and connect the main output of the generator to input A of the counter. Built-In Math Processing With the built-in math functions, you can make post-processing operations like scaling and offsetting an easy benchtop task... -
Page 12: Under The Settings Menu
The measuring speed can be increased substantially if you set the trigger levels manually once, before a lengthy measurement sequence starts. Press INPUT A and choose MAN for the MAN/AUTO setting. Now press Trig to open the trigger level value input menu. Enter a level of +0.5 V. -
Page 13: Fall Time
Fall Time Phase Fall time is measured in a similar way by selecting Fall Time So far the counter has shown the timing relationship between instead of Rise Time above. the TTL and the main output of the generator as a time delay. You can also show this as phase shift between the signals. -
Page 14: Summary
Is this a feature? Well, yes and no. Yes, since this function gives touch-hold characteristics. No, since interrupted measurements giving false readouts may be misinterpreted by automatic test equipment and can even cause control SW to halt. The solution to this problem is the time-out function. –... - Page 15 CONTACT PENDULUM INSTRUMENTS SWEDEN phone +46 280 41122 info@pendulum-instruments.com UNITED STATES phone +1(866) 644-1230 us-office@pendulum-instruments.com © Pendulum Instruments 2021 March 06, 2020.
