Query :SOURce2? Query source value for speciﬁed limit

Description These commands are used to deﬁne the digital output “fail” patterns for the

speciﬁed tests (0 to 7, 3-bit; 0 to 15, 4-bit). Note that the “fail” patterns for

Limits 2, 3, and 5-12 apply only to the grading mode.

Tests are performed in the following order:

1. Limit Test 1

2. Limit Test 2

A. Lower Limit 2

B. Upper Limit 2

3. Limit Test x, where x = 3, 5-12 in ascending numerical order.

A. Lower Limit x

B. Upper Limit x

The ﬁrst failure in the test sequence determines the bit pattern for the digital

output port. Subsequent failures in the test sequence will not change the

deﬁned digital output pattern. Note that the output value can be speciﬁed as

a binary, octal, decimal, or hexadecimal value.

NOTE 16-bit I/O is available with the 2499-DIGIO option. The maximum 16-bit output

value is 65535.
