Models 2500 and 2502 User’s Manual SCPI Command Reference 17-47
NOTE Timestamp values are approximate. See Section 8 for details.
STATus — A status word is available to provide status information con-
cerning Model 2500 operation. The 24-bit status word is sent in a deci-
mal form and must be converted by the user to the binary equivalent to
determine the state of each bit in the word. For example, if the status
value is 65, the binary equivalent is 0000000000001000001. Bits 0 and
6 are set.
The significance of each status bit is explained as follows:
Bit 0 (OFLO1) — Set to 1 if channel 1 measurement was made while in
over-range. Cleared to 0 otherwise.
Bit 1 (OFLO2) — Set to 1 if channel 2 measurement was made while in
over-range. Cleared to 0 otherwise.
Bit 2 (FILTERED) — Set to 1 if either channel 1 or channel 2 measure-
ment was made with the filter enabled. Cleared to 0 otherwise
Bit 3 (COMPLIANCE1) — Set to 1 if the channel 1 voltage source is in
compliance. Cleared to 0 otherwise.
Bit 4 (COMPLIANCE2) — Set to 1 if the channel 2 voltage source is in
compliance. Cleared to 0 otherwise.
Bit 5 (NULL1_ACTIVE) — Set to 1 if channel 1 REL (CALC3) is
enabled. Cleared to 0 otherwise.
Bit 6 (NULL2_ACTIVE) — Set to 1 if channel 2 REL (CALC4) is
enabled. Cleared to 0 otherwise.
Bit 7 (LIMITS_ACTIVE) — Set to 1 if a limit test (CALC7) is enabled.
Cleared to 0 otherwise.
Bit 8 (LIMIT_A) — Encoded limit test summary bit. See grading and
sorting modes in “Limit test bits” below.
Bit 9 (LIMIT_B) — Encoded limit test summary bit. See below.
Bit 10 (LIMIT_C) — Encoded limit test summary bit. See below.
Bit 11 (LIMIT_D) — Encoded limit test summary bit. See below.
Bit 12 (LIMIT_HIGH) — Limit test 3 - 6 failed high. See below.
Bit 13 (CH1_OUTPUT) — Set to 1 if the channel 1 source output is on.
Cleared to 0 otherwise.
Bit 14 (CH2_OUTPUT) — Set to 1 if the channel 2 source output is on.
Cleared to 0 otherwise.
Bit 15 — Not used.
Limit test bits Bits 8 through 12 flag pass/fail conditions for the various limit tests. The
bit values for the grading and sorting modes are covered below. See
:CALC7:CLIM:MODE and associated commands in “Calculate sub-
systems,” page 17-22.
