Those Instructions which take
time
(i.e. measurement duration) as a parameter use units of seconds
if the 's' suffix is specified, or tenths of a second if not, e.g.:
MEAS_DATA_JITTER(4.5s)
or
MEAS_DATA_JITTER(45)
would both measure Data Jitter over a period of 4.5 seconds.
Boolean operators
These Instructions cause a boolean operation to be performed on the Test Register, and are used to
operate on the result of a previous TEST_.. Instruction (normally TEST_REF_STATUS or
TEST_CSBYTE(n), see above). Conditional branch Instructions may then be used to vary action
according to the results of the boolean operation.

Bitwise AND operation: new result = old result AND value

Bitwise XOR operation: new result = old result XOR value
'
value
' is a 16-bit word value expressed either as hexadecimal with a following 'h', binary with a
following 'b' or decimal without either. '
value
' is enclosed in brackets.
Sequence flow
These Instructions cause the DSA-1 to branch or 'jump' to another part of the Sequence. Care should
normally be taken never to branch outside the current Segment; although this is not specifically
prevented, it is only occasionally useful and, if used unwisely, can cause unpredictable results.
The conditional branch Instructions enable different responses to occur depending on the results of
previous TEST_.. or MEAS_.. operations. All JUMP_.. Instructions have a label description (starting
with a '@' character) as their last parameter. Some also have a hexadecimal, decimal or binary value
as the first parameter. Note that all the JUMP_.. Instructions have a 'short form' as shown in the list
below.
Conditional branch Instructions act upon the current contents of the Test Register but do not change
it, so that multiple JUMP_.. instructions may be used to test the same result several times.
