Event Timer A032-ETFirst two parameters are defined in corresponding configuration file for ET-server program andmust be the same. The last parameter is the size of dynamically allocated arrays, in which alltiming data are stored for next processing and saving. Any text editor can be used to correct thecorresponding parameter values in the configuration file.For convenience, you can place a shortcut to the executable program APPClient.exe on yourdesktop. Double click the shortcut or APPClient.exe icon in the working directory starts the ETclientsoftware. When started, the program opens a main control panel “DEMO SubsystemA032.1-C1” (Fig.B-2).To uninstall A032.1-C1 Software you should use the standard MS-Windows function “Add orRemove Programs”.3. Control panels of the A032.1-C1The main control panel of the A032.1-C1 (Fig.B-2) provides mainly the functions related with themeasurement On/Off, presentation and filing of the measurement results. However before anymeasuring some preparatory procedures should be performed. Click the button SERVER to callout an accessory panel “ET-Server A032.1 Control” (Fig.B-3), which provides the Sessionestablishment and the preparatory procedures (“Scaling”, “Time synchronization”, “Timemonitoring”, “Setting”) for the following measurements.Fig.B-2.

Event Timer A032-ET3.1. Accessory panelThe accessory panel (Fig.B-3) contains four dedicated sub-panels titled according to their basicfunctions:- Session with Server- Timer Calibration- Timer’s clock- Server Setting3.1.1. Session with Server. This sub-panel provides the Session establishing. This is the firstaction that must be made before any other activities. Clicking the button Open initiates theTCP/IP connection to the predefined ET-Server. If the ET-Server is in action and is free fromother Sessions the Session has to be established. In this case the title “Session with Server”changes in colour from red into black. In other cases the message indicating the reason ofreject appears. Clicking the button Close closes the earlier established Session and makes theET-server available for any other ET-client.3.1.2. Timer calibration. This sub-panel provides functions corresponding to the procedure“Scaling”. Click the button Start to activate this procedure, resulting in correction of parametersfor data processing in view of current operating conditions. At the end of the procedure a selfestimationof the timer’s expected precision is performed.In case of successful calibration a currently offered timer’s precision (RMS) appears. Normallythis precision should be surely less than 10 ps and is written in black. In other cases themessage indicating the reasons of calibration impossibility appears, and RMS value remainswritten in red.The procedure should be necessarily made after warming up (about 1 hr) of the ET-device andif the operating conditions have been essentially changed in temperature (± 5 0 C approx.).Without timely executing of this procedure the measurement error can increase.3.1.3. Timer’s Clock. This sub-panel provides synchronization of the timer’s clock with the sync1 pps pulses from an external source and PC clock, monitoring of the timer’s clock and epochtime correction if desired. The mentioned procedures are not compulsory in online application ofthis subsystem, but the synchronization can be useful if you want to get the synchronized timetagsfor their further offline processing.Clicking the button Synch activates the procedure “Time synchronization”, resulting indisplaying of time when this synchronization has been performed. In the case of commandreject the message indicating the reasons of such rejection appears.Clicking the button Check activates the procedure “Time monitoring”, resulting in displaying thetimer’s clock. The clock’s readouts can be manually corrected at will. In this case the number ofseconds in correction is displayed and further will be sent to the ET-sever as settingparameters. In the case of command reject the message indicating the reasons of suchrejection appears.Click the button Stop to interrupt the procedure “Time monitoring” and go to the next procedure.3.1.4. Server setting. This sub-panel provides setting the parameters for further measurementin accordance with the values in control fields:Triggering: either INT (internal) or EXT (external)Cycle duration [ms] (is adequate to the period of ET-device monitoring)Number of Events (is adequate to the amount of TD-blocks that will be read from the ETdevice)27
