Display Calibrations announces the development of a brand new AccuPel video generator with greatly enhanced features.
The AccuPel DGA-6000 Ultra combines a 4K video generator with a 4K HDCP 2.2 analyzer. The AccuPel DVG-5000 is now discontinued.
The DGA-6000 Ultra is an exciting innovation in...
EDIT: Ok, for what its worth, here is the correct photo.
I took a screenshot that shows both problems at once.
The bottom graph is a time signal (oscilloscope style) of the generator output. Cursor #1 bottom graph marks where I started REW's sig gen. Cursor #2 bottom graph marks the point...
using beta 11, to reproduce;
open signal generator
select White PN
check both low cut and high cut (e.g. 50 and 200)
verify output in tool of choice
output is for 0-highcut Hz
it seems the low cut is ignored, not sure if intentional
pink pn does respect both check...
I'm used to run REW for quite long sessions, and after a certain time different kinds of problems appear with the signal generator :
1. At the end of the sweeps, apparition of strange sounds like echoes.
2. When using a continuous sine signal, production of a very distorted one, see the...
I am having a problem with the signal generator and the sine wave sweep used for room measurements. The amplitude of the generator decreases as the frequency of the output increases. This occurs with REW running under both OS X and Windows 7. I have read and reread the instructions...
Ive played with REW in the past on 2 different machines. At some point i was able to get input working but it was intermittant sometimes worked sometimes didnt.
Now it just doesnt work no matter what input i try.
Has anyone managed to get this to work reliably with jack.
Running kx studio...
Configurationing REW for the first time and have reached the point to test and measure. In attempting to use the signal generator for pink noise, an error msg appears saying the signal generator is unavailable. Have been unable to determine why and therefore unable to proceed with measuring...
I've used REW to measure headphone FR successfully for 3 years.
I can Generate a 300 Hz Square Wave with REW's Generator but cannot determine If it's possible to record the generated signal.
Is it possible to use REW's Generator to produce a 300 Hz Square Wave and record/measure the results...
In REW I'm wondering if there is a way to add a calibration factor to the Generator basically in the same way you do for the SPL Meter. It would be nice to type in a real SPL value instead of manually converting dBFS to dBSPL. If that's not possible, I'd love it if that feature could be added...
Can anyone tell me why the REW tone generator won't run - the message I get on cliking the 'measure' button is:'unable to start generator'. Same thing happens just clicking on the 'play' symbol in the generator window. My EMU sound card is correctly set up in 'Preferences'.
I have started to run the setup documented here  with the same microphone, a Scarlett 2i2 USB interface and a Lenovo W510 running Ubuntu 12.04. I have installed REW 5.01. My DMM is a Tenma 72-7720.
In order for me to get the 1.1 reading on the Tenma DMM I have to set the Output and Playback...
AccuPel DVG-5000 Video Test Pattern Generator Firmware Update 4
Adds ability to display sequential User Colors via USB command with significantly enhanced speed.
Adds ability to define and display User Colors via remote control and OSD with 8-bit and 10-bit precision.
There some good news for the HT calibration community. After some HT enthusiast / Pro calibrators request for Accupel DVG-5000 Video Test Pattern Generator hardware support, LightIllusion worked to make this happen; to support the users that had AccuPel at their calibration gear already and now...
At ISE show AMSTERDAM, DVDO Team was showing their new AVlab TPG, a 4K test pattern Generator that can be use even with Calman or Chromapure.
I will soon get a press sample to write a review about it in combinaison with Chromapure pro
I have been using the REW5 Spectrum Analyzer and comparing it to that of Virtins Multi-Instrument both with an external EMU0404 soundcard in 24-bit mode. Generally, the calculation of THD agrees between both but the THD+N as calculated by REW5 is always much higher (more than a factor of 2). Is...
SpectraCal releases first portable 4K video test pattern generator
VideoForge 4K offers huge pattern set for 4K display testing and calibration
(Seattle, WA) – February 5, 2013 – As display manufacturers roll out new screens capable of 4K resolution, SpectraCal, Inc. released today a...
Hello Folks, I am using ver 5 beta9 and I am having some random problems when measuring small sweep at low frequency.
I am basically measuring freq resp between 5 to 500 Hz and sometime, randomly, the sweep generator or the metering routins goes crazy reporting absourd low levels and unatural...
Hello Folks, anybody never used the Generator -> Square Wave option?
I am using ver 5 last beta 9.
All the other Generator options look working as expected, so I believe it to be a sw bug.
Looking forward for the fixing.
