Example 2: Use of the :IDATa command
Update 9 bits of store number 5 starting at bit 3. Let the new data bits be 1, 0, 0, 1, 1, 0, 1,
1, 1 (binary). Then query these 9 bits.
Method 1: using data packed 1 bit per byte.
PATT:FORM PACK,1
PATT:UPAT5:IDAT 3,9,#19<data>
where
3 = the start bit
9 = the number of bits
# = the start of the header
1 = the number of decimal digits to follow forming the
length
9 = the length of the data block that follows
<data> = 9 data bytes containing binary 00000001
00000000
00000000
00000001
00000001
00000000
00000001
00000001
00000001
PATT:UPAT5:IDAT? 3,9
would return #19<data>
where
# = the start of the header
1 = the number of decimal digits to follow forming the
length
9 = the length of the data block that follows
<data> = 9 data bytes containing binary 00000001
