Notes
1.
May take up to
5
ms Longer
if the
relative mode
is
enabled.
2. Can save 10 ms if all Level
correction
is
disabled with special

3.
Add 20 ms when frequency changes from greater than or equal
to
245
MHz to Less than 245 MHz. Subtract 20 ms from
frequency hardware-
settling time
in
this
case.
4.
Edits and steps may take up to
5
ms Longer than the
programming
function directly.
5.
Add
5
ms
when the Attenuator settings
change.
6.
Recalls vary considerably depending on the stored data.
Maximun
is
approximately 250 ms.

TIMING OPTIMIZATION
Timing depends upon
the interface
modes
selected.
Read
the
paragraphs
on
Interface
Mode Commands
for a
complete description of the interface
modes.
The
transfer of
commands
from
the
IEEE-488
controller to the
Generator can never be
processed in parallel
with anything
else.
The
transfer
of
commands
usually
happens
simultaneously, regardless
of
which
interface
mode
is
selected.
The
parsing of the
command and programming
the
new
instrument
state
is
performed
one message unit at
a
time.
The
