The histogram file contains a list of variables and definitions booking for
graphical data representation. Any variable name defined in file.ACQ
or file.EQU can be used in the histogram file with an incremental
condition flag attached to it (from file.TST.) The definition of
histogram is done in a single line.The total number of histograms should not
exceed maxhis nor should the total number of bins allocated for them
exceed maxtotbin. Each individual histogram can have a maximum of
maxhstbin bins.Two types of histogram are available in SusiQ.
standard histogram type The definition is composed of its name,
number of bins, low and high limit, conditional test name to be applied to it
and the actual data variable to be histogrammed.
Histogram name |
The name should be unique among the histogram names |
Number of bins |
Allocation of the number of bins for that histogram. 'maxhstbin' defines the system limit. |
Low limit |
Defines the lower data limit for the histogram |
Up limit |
Defines the upper data limit for the histogram |
condition name |
pre-declared flag name on which the histogram will be incremented |
Data variable |
pre-declared ACQvar or EQUvar name which contains the data to be histogrammed |
chart recorder type This second histogram type allows you
to monitor a variable as a function of time or of a test condition.
It is sometimes interesting to record the variation of a data word as a function of time. If for example one CAMAC module reads a temperature, pressure or voltage, SusiQ allows you to display, check and take action based on the value of that parameter. If the CAMAC module has its own reading cycle with a LAM generation, SusiQ can be applied in the Standard acquisition mode. If the module does not generate a LAM, SusiQ can do it using the Time based Self LAM generator mode. This mode is required if further action or readout has to be performed before receiving the LAM. Finally if no LAM is required then Time based acquisition mode is sufficient. This chart recording format contains the chart name, number of bins, low and high limits, the time keyword followed by the time interval in seconds or the test keyword followed by the test name and finally the actual data variable name to monitor.
Chart name |
The name should be unique among the histogram and chart names |
Number of bins |
Allocation of the number of bins for that chart recorder. Each bin will be a time interval. |
Low limit |
As the time interval is already define in file.ACQ, this value is disregarded. Put 0. |
Up limit |
As the time interval is already define in file.ACQ, this value is disregarded. Put 0. |
then |

TIME |

2]This time defines the minimum time interval between two updates. Depending on several speed factors (CPU,CAMAC access, Test package length, User interrupt etc...], this time interval can vary drastically. Note that if any of [D],[S],[H],[M],[N]... and all intermediate pages of Susiq commands are invoked, the acquisition will be frozen which will delay the update of the chart until the next histogram update.
