4-5
Byte Character Meaning
2 0,1,2,3 The range on which this measurement was taken.
3 R,L,C The major parameter type if querying the major
value.
Q,D,R The minor parameter type if querying the minor
value.
4-N value The measurement value in exponential notation. If
the measurement is invalid, overloaded, or out of
range 9.9999E20 is returned. The units of the value
are Ohms for R's, Henrys for L's, Farads for C's, and
percent for percent deviation.
An example of a verbose ASCII response is the string "G2R1.234E-6".
Concise ASCII This format returns only the measurement value described for verbose ASCII
results. An example of a concise ASCII response is the string "1.234E-6".
Verbose Binary This format returns both status and measurement values as a sequence of 8-
bit binary bytes. The bytes returned are detailed below:
Byte Value
Meaning
1,2 '#0' The ASCII values # and 0 (23h and 30h) are header
information indicating IEEE binary block data output.
3 status An encoded status byte. The bit values are given by:
xxxx0000 Measurement Good. No errors.
xxxx0001 Invalid measurement, no measurement, A/D error.
xxxx0010 Measurement overloaded.
xxxx0100 Underrange. The measurement value is below the
nominal range of values for this measurement range.
xxxx1000 Overrange. The measurement value is above the
nominal range of values for this measurement range.
xxxx1111 Out of Range. The value is above the SR715/720's ability
to measure on this measurement range.
xx00xxxx R+Q
xx01xxxx L+Q
xx10xxxx C+D
xx11xxxx C+R
00xxxxxx Range 0
01xxxxxx Range 1
10xxxxxx Range 2
11xxxxxx Range 3
4-7 value The measurement value is returned in 4 byte (32 bit)
IEEE standard single precision floating point format. The
least significant byte is sent first (the same as PC
format). The value 9.9999E20 returned if the
measurement is invalid, overloaded, or out of range.
8 linefeed Linefeed (10h) is the result terminator (sent with EOI on
GPIB).
