Keithley 2016 - [:Event]? Command

[:EVENt]? command
[:EVENt]?
:STATus:MEASurement[:EVENt]? Read Measurement Event Register
:STATus:OPERation[:EVENt]? Read Operation Event Register
:STATus:QUEStionable[:EVENt]? Read Questionable Event Register
Description These query commands are used to read the event registers. After sending one
of these commands and addressing the Model 2016 to talk, a decimal value is
sent to the computer. The binary equivalent of this value determines which bits
in the appropriate register are set. The event registers are shown in Figure 5-4,
Figure 5-5, and Figure 5-6. Note that reading an event register clears the bits in
that register.
For example, assume that reading the Measurement Event Register results in an
acquired decimal value of 544. The binary equivalent is 0000001000100000.
For this binary value, bits B5 and B9 of the Measurement Event Register are set.
Measurement Event Register:
Bit B0, Reading Overflow (ROF) — Set bit indicates that the reading
exceeds the measurement range of the instrument.
Bit B1, Low Limit 1 (LL1) — Set bit indicates that the reading is less than
the Low Limit 1 setting.
Bit B2, High Limit 1 (HL1) — Set bit indicates that the reading is greater
than the High Limit 1 setting.
Bits B3, Low Limit 2 (LL2) — Set bit indicates that the reading is less than
the Low Limit 2 setting.
Bits B4, High Limit 2 (HL2) — Set bit indicates that the reading is greater
than the High Limit 2 setting.
Bit B5, Reading Available (RAV) — Set bit indicates that a reading was tak-
en and processed.
Bit B6 — Not used.
Bit B7, Buffer Available (BAV) — Set bit indicates that there are at least two
readings in the trace buffer.
Bit B8, Buffer Half Full (BHF) — Set bit indicates that the trace buffer is
half full.
Bit B9, Buffer Full (BFL) — Set bit indicates that the trace buffer is full.
Bits B11, Reading Underflow (RUF) — Set bit indicates that the reading is
too low for the present measurement range.
Bits B12, Distortion Frequency Overflow (TFO) — Set bit indicates the
frequency is too high for distortion measurements.
Bits B13, Distortion Frequency Underflow (TFU) — Set bit indicates the
frequency is too low for distortion measurements.
Bits B14, Distortion Shaping Filter Error (TSF) — Set bit indicates the
frequency not defined for the shaping filter in use.
Bit B15 — Not used.
