FEATURES A f

9、unctionally organized keyboard/softkey structure in combination with an interactive menu-display serve the user in setting up and entering parameters for triggering, capturing, comparing and counting the activities of the system under test. The extensive triggering capability of the 7 sequential tri

10、gger-words, that can be combined with clock and trigger-qualifiers, permits capturing data from complex system activities or from deep branched or nested loops. Each trigger-word has the same width as the number of input channels of the various models. The sequence of the different trigger-words use

11、d can be defined by the use of an IF, THEN, ELSE algorithm, with the possiblity of placing a certain amount of delay between the statements. In this mode triggering can be selected as True or False. A notable feature of this mode is that the selected trigger sequence can be specified as true or alte

12、rnatively as not true. This latter mode is called Trigger on Sequence Break mode and provides the capability of triggering when a defined repetitive pattern (eg. a loop or a polling sequence) is broken or not executed in the specified order. The moment of capturing data can be delayed by states and/

13、or trigger occurrences and/or time. The Logic Analyzer can also be used for making time measurements. A readout of the elapsed time between two points in a programm can be obtained. Special features of note here are the COMBI and the SYNC modes. The COMBI mode allows the state section to be triggere

14、d by the timing section or vice-versa, while in the SYNC mode the displays of a number of timing channels are cross-referenced with state sampling. This enables analysis of critical state/time relationships. Data to be captured is clocked into the analyzer on selected clock edges of one of the three

15、 selectable clock sources. For each clock used, there are up to four qualifiers available. In the COMPARE mode, a comparison can be made between captured data and stored data in the formats: List or Timing. The instrument automatically stores the current mode-and function instrument-setting, when th

16、e mains voltage supply is switched off. After switching on) the instrument comes up in the initial default mode- and function setting. All analyzer models can be equipped with the option (non-volatile memory) to store up to 4 additional settings. Here each setting is stored and retrieved under a lab

17、el. PM 3551A Operating manual Chapt. 1 SW 2.0 JGB401 October 13, 1983 1.7 In the TIMING mode, glitches of a duration of as little as 5 nanoseconds can be captured from the data-stream. The PM 3551A can be equipped with a 4 channel 300MHz timing option, independently of the presence of the 8 channel

18、50 MHZ section. This allows high precision timing measurements. Other options are the options board with standard RS232C printer output. This board can be equiped with an GPIB control interface, or a RS232C control interface, both providing full remote control of the instrument. The options board is

19、 also a prerequisite for installation of disassembly- packages, and the non-volatile setting memory. The disassembly-packages allow the user to view captured data in the mnemonic language of the most currently available 8 and 16-bit microprocessors. Data is entered into the analyzer via 8-channe1 po

20、ds, each provided with its own threshold adjustment. A variety of convenient Pod-attachments are available for connecting the system under test to the analyzer. A comprehensive built-in diagnostic program can be used as an aid to test the various functions of the analyzer and to assist in fault-find
