I still reccomend a Tektronix either the 465B or the later 2465 which is quite a bit lighter. I recently converted to the 2465 because it is not so heavy and I was able to aquire a really nice one for about a hundred dollars. The downside of the 24XX series is the lack of available replacement IC's as Tektronix had all of them custom made. All of the sweep amplifiers and power deflection stages are monolithic ICs and the horizontal sweep IC is extremely prone to failure. You more or less have to keep a parts unit around to be able to keep these models running for the long term. On the other hand if you don't mind it's weight the 465B is still the most durable and reliable scope ever produced by anyone. I second Mikes suggestion on sound analyzers.

I got one at Mark's suggestion. Good piece of equipment. Size and weight are secondary.  |  IP: Logged John Hawkinson Film God Posts: 2273 From: Cambridge, MA, USA Registered: Feb 2002 posted 10-02-2009 04:12 PM                     Raise your hand if you have a rackmount oscilloscope in your booth [or a waveform monitor]? (No, we don't. I've been tempted, but the rack space is just too dear...) --jhawk  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Steve  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 10-02-2009 11:58 PM                     I have two Videotek TMV-621 wvfm/vector scope combos. By far the best scopes of their type I've used. Tektronix may have a better one but at probably 6 times the price. I settled on Videotek for my repair bench because they are well made., parts are easy to get(they are owned by Harris), the crts use P-4 phosphor and have a white trace that IMHO is alot easier on the eyes and they are more flexible than Tektronix in the same price range. I am sending my Tektronix Wfm and vector scopes to another Film-Techer.

Thought about it for a while but I took a couple of aspirin and laid down for a while until the feeling went away. Like you, rack space is short.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 10-03-2009 10:39 AM                     The combination monitors like the TVM-621 and TVM-675 are for those that don't have alot of space!!!b They monitor audio as well. Similar versions are made for digital video. Mark  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 10-03-2009 12:28 PM                     Keeping with the Videotek/Harris theme and economizing on rackspace...check out their 1U (plus conventional monitor) solution...I've seen them in action and they are way cool. http://www.broadcast.harris.com/products/test/vtm.asp Steve  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 10-03-2009 12:43 PM                     Yep, those things are all over the place on Farnsworth Peak, mainly located in the transmitter equipment support racks. The convenience is there because it can display all pertinent info on the same screen at once. However, it doesn't REALLY save on room because you still need some sort of composite or VGA monitor to display on and that also normally goes in the rack. You could use an on line monitor and switch back and forth but then it becomes inconvenient. Tektronix has had similar units for as long as Videotek. I miessed a Tektronix unit on E-bay for a BIN of just $120.00! Mark  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

You can also home in on the specific function of interest and really get some precise readings or leave it in the general mode of showing smaller versions of everything.
