zero, and the fourth indicates the version number of the
IEEE-488 interface software.

face software version 4.0
3-21. N (Numeric Entry Command)
Format Explanation
Ncnumeric entry> Where <numeric entry> is one
of the following:
<signed integer>
<signed real number without
exponent>
<signed real number>E<signed
exponent>
Example Explanation
"N12001" Enters the five-digit integer 12001
"N-1.23E2" Enters -123 x
102
"Nc15433E-1" Enters 1.5433 x 10'
The N command enters numeric values for use with subse
quent Put commands. The intepretation of the numeric
value depends on which
Put command it is used with.
The
E can be used within an N command for entering an
exponent of 10. The N can be used without an E, but an E
requires a prior
N. The exponent can be any integer from
-9 to +9.
The mantissa may exceed 5-112
digits. The 8840A
accurately calculates the appropriate exponent and then
disregards all but the first 5-1/2 digits of the mantissa.
However, a syntax error will occur if the numeric
entry
overflows the input buffer.
Example Explanation
"N123456789" Enters +I23456

3-22. Put Commands
The Put commands PO through P3 set up the 8840A's
configuration and operating
modes by entering ("putting")
information in the appropriate registers. The put com-
mands are described further in the following paragraphs.
3-23. PO (Put instrument Configuration)
Format
Example
3-1 0
Explanation
Where <fist> is a four-digit integer
interpreted
as arguments for the F, R,
S, and
T commands.
Explanation
"N3120 PO"
Identical tq F3 R1 S2 TO. Sel
WIRE kS2 function, 2008
sample rate, continuous trigger.
The PO command allows broadside loading of the
Fimc-
tion, Range, Reading Rate, and Trigger Mode comm ds
(F, R, S, and 7'). The codes for these commands are 1 ted
in Figure 3-5.
P
A numeric entry for PO must be within +I000 and +6?24.
Each of the four digits must not exceed its
maxi~um
allowed value (6, 7, 2, and 4, respectively) or an +nor
message
will occur and the instrument configuration lwill
remain unchanged The
entry may be expressed a$ an
integer, real number, or real number with exponent, as
described under the N command. Any fractional pait is
ignored.
Example Explanation
"N3112 PO" Sets the 8840A to
F3, R1, S1, and T2.
3-24. PI (Put SRQ Mask)
Format ExplWm
NcSRQ mask>Pl
Where SRQ mask is a two-digit
integer from
00 to 63.
'
The P1 command is used to prbgram the 8840A to d;lake
service requests on user-specified conditions. The
digit code for
the SRQ mask is interpreted in Tab1
under the G1 command. For more about -the SRQ
dask,
see paragraph 3-47. I
Numeric entries for the P1 command must be betw n 0
and
43 (inclusive), or an eqr will occur and the RQ
mask will remain unchanged.
'Iihe entry may be expr
ignored.

Example Explanation
"N0.17E+2 PI" Sets SRQ hask to
17. Enables 6RQ
on data aMlable or overrange.
~
"N1 PI"
Sets SRQ
mask to 01. (A leading zero
is assumed.) Enables SRQ on bver-
range.

Ncvalue>P2 Where due> can be an integer1 real
number, or real number with
txpo-
nent, as described under the N com-
mand.
Example Explanation
"~1 ~2"
If the 8840A
is in VDC, the next
calibration input expecteh is
1.00000V dc.
The P2 command is used to enter variable input calib tion
values just lib the front panel VAR IN button. To Xcept
