3 Features and Functions The following table shows the different combinations of front- panel annunciators that may appear while using alarms. In addition to being stored in reading memory, alarms are also recorded in their own SCPI status system. You can configure the instrument to use the status system to generate a Service Request (SRQ) when alarms are generated. Refer to the Agilent 34980A Programmer’s Reference Help file for more information on the Status System. An alarm is enabled on the displayed channel. The indicated HI or LO limit is being configured on the indicated alarm (shown while in the Alarm menu). An alarm has occurred on one or more channels. The behavior of the Alarm Output lines tracks the alarm annunciators on the front panel. The Alarm Output lines have been cleared but alarms remain in the queue. The default values for the upper and lower alarm limits are “0”. The lower limit must always be less than or equal to the upper limit, even if you are using only one of the limits. For details on configuring alarms on the digital modules, see “Using Alarms With the Digital Modules” on page 138. A Factory Reset (*RST command) clears all alarm limits and turns off all alarms. An Instrument Preset (SYSTem:PRESet command) or Card Reset (SYSTem:CPON command) does not clear the alarm limits and does not turn off alarms. Front Panel Operation: Alarm > LOW LIMIT > HIGH LIMIT > THIS CHANNEL ALARM After selecting the lower and upper limit for the selected channel, assign one of the four alarm numbers. Note that the instrument does not start evaluating the alarm conditions until you exit the Alarm menu. Remote Interface Operation: To assign the alarm number to report any alarm conditions on the specified channels, use the following command (if not assigned, all alarms on all channels are reported on Alarm 1 by default). OUTPUT:ALARM2:SOURCE (@2001,2012) To set the upper and lower alarm limits on the specified channels, use the following commands. CALC:LIMIT:UPPER 5.25,(@2001,2012) CALC:LIMIT:LOWER 0.025,(@2001,2012) To enable the upper and lower alarm limits on the specified channels, use the following commands. CALC:LIMIT:UPPER:STATE ON,(@2001,2012) CALC:LIMIT:LOWER:STATE ON,(@2001,2012) 134 Agilent 34980A Mainframe User’s Guide
Viewing Stored Alarm Data Features and Functions 3 If an alarm occurs on a channel as it is being scanned, that channel’s alarm status is stored in reading memory as the readings are taken, and in a separate alarm queue. The alarm queue the only place where non- scanned alarms (e.g. alarms during a monitor, alarms generated by the digital modules) get logged. You can store at least 500,000 readings in memory during a scan. You can read the contents of reading memory at any time, even during a scan. Reading memory is not cleared when you read it. Each time you start a new scan, the instrument clears all readings (including alarm data) stored in reading memory from the previous scan. Up to 20 alarms can be logged in the alarm queue. If more than 20 alarm events are generated, only the first 20 alarms are saved. The alarm queue is cleared only by the *CLS (clear status) command, when power is cycled, or by reading all alarm entries. Front Panel Operation: View > ALARMS From the front panel, you can view the first 20 alarms in the queue. After turning the knob to the desired channel, press the left or right arrow keys to view the alarm reading. The alarm queue is cleared when you read the alarms. The annunciators indicate which alarm is being viewed. Remote Interface Operation: The following command reads data from the alarm queue (one alarm event is read and cleared each time this command is executed). SYSTEM:ALARM? The following is an example of an alarm stored in the alarm queue (if no alarm data is in the queue, the command returns “0” for each field). 1 2 3 2.61950000E+01 C,2004,11,21,15,30,23.000,1003,2 Reading with Units (26.195 °C) Date (November 21, 2004) Time (3:30:23.000 PM) The following command retrieves scanned readings and alarm data from reading memory (the readings are not erased).
