Changes
of P900 versions from 1.0 and up
Changes from version 1.0 to 1.0-a
a)
Fully
mouse support added to edit and modify reference curves.
Changes from version 1.0-a to 1.0-b
a) New filter MOD-FIX added. This filter is a
FIX-HP filter where the filter setting automatic turn over to a tracked filter
5 times less the corner HP filter frequency.
This give a better detection just before the FIX-HP filter begin to meet the
FIX frequency corner. The MOD-HP is terminating the data at the frequency
corner.
Changes from version 1.0-b to 1.0-c
a)
List
of stored types in Utility Process data did list 64 types. This is changed to
512 types.
b)
In
Utility Process data Replace part of curve the Min curve did not work for BL
curve.
This is corrected.
c)
A
new test “R-23” have been added. This is relative distortion test, a ratio
between some distortion types.
d)
In
Edit-mode Select Display function have been expanded to selection a single
curve in each display channel (A-D).
e)
In
Run-mode Select Display under Cursor have been expanded to selection a single
curve in each display channel (A-D).
f)
In
Utility-mode Process Statistical Data, Select Display under Cursor has been
expanded to selection a single curve in each display channel (A-D).
g)
Import
2. And 3. Reference curves used in channel A did not check if the curves were
set off if present. This is corrected.
h)
In
Edit-mode curve convert, Scale, T-curve and Gain Adj. submenus have been
improved due to no d)
i)
The
update speed of graph curves updated. In utility process mode with approximate
3-4 times.
j)
A
second brand of dongle has been added to system.
k)
IO
input bit 0-3 inverted to give a better interface handling.
l)
When
chain was used in run-mode and the first and last test used different test
points the last test was displayed with the first test no of points. This is
corrected.
m)
The
maximal end frequency of a sweep changed from 30000 Hz to 50000 Hz if sample
frequency is 192000.
n)
When
sample frequency is 192000 the selection of upper filter limit is 22, 34, 45 or
52 KHz.
o)
Sync
Burst function at polarity test did not work. This is corrected.
p)
In
edit mode the display shows some garbage in channel A when arrow up or arrow
down was used and the number of display was 2 or 3. This is corrected.
q)
At
the sweep a “Slow” function added. The minimum step rate between each frequency
step can be slowed approximate 4 times slower than normally sweep.
This reduces the delay between sound from speaker and microphone
depending distance. Example 10 kHz could
be displayed at 15 kHz if sweep speed was too fast.
r) When
output compress function was used ref channel was not stored. This is
corrected.
s) Bl
mode corrected. The delay was faulty implemented. This corrected.
t) The
Ai function did not work correct in run-mode. This is corrected.
u) Sync
Burst renamed to Sync delay and a spate delay added.
u) Process
delay added.
Changes from
version 1.0-c to 1.0-d
a)
If
chain was used and resonance test was used in channel C the curve was changed
to reject color if first test was called and rest was test was displayed. Test
was ok. This is corrected.
b)
If
R2 test was used and later disabled the test got a reject as total test even it
was not used. This is corrected.
c)
If
chain and System2 was used and the output level was different from first and
second test channel C was failed du to mix in the first and second test. This
is corrected
Changes from
version 1.0-d to 1.0-e
a)
The
display when using an external amplifier with a sense resistor updated.
b)
If
chain was used and the last called and the setup was different in no of points
and frequency setup from the first one the system used the last parameters for
the setup the first. This for Phase, Bl and R23 measurements. This is
corrected.
c)
If
in setup the F-test and EBP was reset and saved, (the f-test and EBP test off),
and the test did show a reject in run-mode.
This is corrected.
d)
A
buffer mish mash in Utility id R23 test was used. This is corrected.
e)
Hi-2
user limit was not stores or read in database.
This is corrected.
f)
Limit
for 2th and 3th reference and R23 limits was not transferred to Log setup. The
backup database. This is corrected.
g)
As
option System 3 have been added the system in Run-mode. Display resolution on
minimum of 1440x900 needed. . P900 pro+.
h)
As
option a chain result for second measurement (first, second and last) have been
added the system in Run-mode. Display resolution on minimum of 1440x900 needed.
P900 pro+.
i)
As
option a chain result for second and third (first, second, third and last) have
been added the system in Run-mode. Display resolution on minimum of 1440x900
needed. . P900 pro++.
Changes from
version 1.0-e to 1.0-f
a)
A
check for max output voltage in setup added (internal max is 14.0 Volt).
b)
In
run mode when win 10 was used some instability could happened in the beginning
of a sweep appear. This is corrected.
c)
In
run mode user number added to data did only work for first measurement. This is
corrected to work for first, second, third and last measurement.
d)
The
Re measurement did not work in chain mode. This is corrected.
e)
Check
for jack plug preset on input (the Extern enabling) is changed from 50 mSec to
100 mSec refresh in Hardware Calibration menu.
f)
Check
for jack plug present has been added in setup menu if output B or Ext is selected.
g)
Info
for invalid input mux selection has been added in setup menu.
