Sencore VP403/VP403C Rental

post #1 of 20
Thread Starter 
Does anyone know where one might be able to rent a Sencore VP403/VP403C for a few days?

And before you ask, yes it needs to be a minimum of a VP403 with the ATSC output (and preferably the clips of the VP403C) - not a VP300, VP400, VP401 or Accupel that do not have the ATSC output.

Thanks!

Interesting question.

How much do these things go for retail?

Greetings

In the $5000 to $6500 range.

More than someone who has a one time use for it needs to spend

Even as a rental, you would be looking at a price that would make you think twice about buying an Accupel.

So you are telling me the Accupel has an ATSC output that isn't listed on its specs?

What (how much) are you willing to rent one for?

No, but I suspect that the ATSC output on the VP403 isn't as useful as you might think/hope.

I'm interested in why you say this.

Whatever it takes within reason - and I am not expecting a blue light special.

Since grayscale is a function of the panel/lamp (not the source) and color gamut is a function of the devices colorfilters/lamp (not the source)- the only purpose of the ATSC output is to do your basic adjustments - brightness/contrast/color/tint.

It is delusional to think that the result of a TV stations broadcast received OTA is going to be anywhere close to a reference generator - the fact is every station will be different.

You simply are not calibrating for the source with an ATSC generator - the source is the TV engineer that frakked up the controls before the broadcast. You are much better off finding the monthly early AM test pattern broadcast.

I think the only people that would require an ATSC generator have a profession that would enable them to pay for it because they need it for some purpose (like a reviewer verifying ATSC tuners). If you are a DIY trying to calibrate your ATSC input - you are wasting your time.

Basically what Kevin said, but I would not have used "delusional" in the the response. There is enough station-to-station and program-to-program variation in broadcast sources that it is rarely worth the effort. If you think you have a problematic tuner, it is probably cheaper to swap it out to see if the issue is resolved, rather than renting an expensive piece of test gear.

It is essentially a high caliber testing device and as thus would be priced accordingly. I would expect the rental price to be in line with other devices of the same caliber, say a good spectrum analyzer etc.

Bravo! A wonderfully written opinon of why most people will not need to use a VP403(C).

Of course, if most people needed to use a VP403(C) they would be available for rent at every equipment rental location in town. The simple fact that they are not leads us to the assumption that most people do not need to rent one - a conclusion that you appeared to come to the same conclusion as the local rental companies - though your conclusion came much later than theirs.

If I just stated "I want someone to design me a Home Theater", then I could hire a homeless person or the $6 sales associate at Best Buy instead of your design and calibration services. However, some of us do have specific needs in mind and that is why we are very detailed in our request.

So with that in mind - and back to the original question - does anyone know where one can rent a VP403(c) for either 3 days or a week?

I asked the question for a specific reason. I have tried using my Sencore many times to set brightness and contrast through my Dish VIP-622. I get very consistent results regardless of local channel selected, 2,3, or 4. It always tells me to set brightness at -7 and contrast at +8 on my RadianceXD. The problem is, I have never trusted these results and invariably set them back to the result I get on that input not going through the VIP-622, i.e., both controls at zero.

So, I agree that the ATSC tuner output is not useful if the results can't be trusted.

Not that your description describes my plan, but as the Sencore is only a signal generator, what device is telling you to set the brightness at -7 and contrast at +8 in the Lumagen. Perhaps that is your issue?

And again, the thread topic is not a debate of does the Sencore unit work, it is simply a request for information on any place that might rent a unit for 72 hours to 7days.

What business purpose do you have for the feature that does not enable you to buy one outright?

Why don't you state your purpose and some very experienced calibrators can tell you if that is the best way to do what you are doing. If you ask for help - people will give it.
If you insist you know better they are less likely to offer help that is not wanted.

If you really need to rent one - you can do that - it cost $325 standard ISF rate and comes with an Sencore/ISF trained technician to demonstrate its use....other than that you are not going to find what your are looking for. The biz model does not exist that would support a rental market. Those that really need it - can afford to buy it because it will pay for itself. Those that can't afford to buy it ...rent the services of those that have already paid for it. If you really want it more than an afternoon - then you need to get really friendly with the right guy - because if they needed it to the point they could justify buying it - then they are using the feature and cannot be without it for a week while you play with it. Only stupid biz buys gear they don't use - but maybe you can find someone that did that and willing to make some money renting it out - but likely they want more than a standard ISF visit.

Where do you live? I actually own the 403C and have used the ATSC for calibration.

Are you located in Canada?

The Sencore has patterns that can be selected in ATSC mode that are used to set brightness/contrast, similar to the patterns used in direct input mode.

So you are talking about the flug patterns where you eyeball the results and set the monitor accordingly - but then you say that your VIP 622 looks different when viewing that? Doesn't that tell you that the VIP622 is out of spec (or what Dish is doing to the broadcast as they re-encode it is out of spec, which isn't all that uncommon).

ATSC OTA broadcasts are much more consistent than the old NTSC broadcasts. After a DBS or MSO gets a hold of them, all bets are off.

No, but if you are planning a vacation on the beach in the South, let me know and perhaps I can help you pay for part of it.
