Measurement event register
The used bits of the measurement event register ( Figure 13-6 ) are described as follows:
• Bit B0, Limit 1 Summary (L1) : Set bit indicates Limit 1 summary information is available in
the :FORM:ELEM STAT element (see Section 16 , “FORMat subsystem” ).
• Bit B1, Limit 2 Summary (L2) : Set bit indicates Limit 2 summary information is available in
the :FORM:ELEM STAT element.
• Bit B2, Limit 3 Summary (L3) : Set bit indicates Limit 3 summary information is available in
the :FORM:ELEM STAT element.
• Bit B3, Limit 4 Summary (L4) : Set bit indicates Limit 4 summary information is available in
the :FORM:ELEM STAT element.
• Bit B4, Limit Fail High (LFH) : Set bit indicates that one of the high limit tests has failed.
• Bit B5, Limits Pass (LP) : Set bit indicates that all limit tests passed.
• Bit B6, Reading Available (RAV) : Set bit indicates that a reading was taken and
processed.
• Bit B7, Reading Overflow (ROF) : Set bit indicates that the current reading exceeds the
selected measurement range of the Model 6482.
• Bit B8, Buffer Available (BAV) : Set bit indicates that there are at least two readings in the
buffer.
• Bit B9, Buffer Full (BFL) : Set bit indicates that the trace buffer is full.
• Bit B10 : Not used.
• Bit B11, Output Enable Asserted (OE) : Set bit indicates that the output enable line is at
digital low (asserted). Source outputs can be turned on.
• Bit B12 : Not used.
• Bit B13, Source 1 Compliance (S1C) : Set bit indicates that the channel 1 voltage source is
in compliance.
• Bit B14, Source 2 Compliance (S2C) : Set bit indicates that the channel 2 voltage source is
in compliance.
• Bit B15 : Not used.
