A basic K4R patch is composed by 1 or 2 PCM samples or sources that can routed to filter in 3 possible modes: normal, twin or double.
Dms Classic Analogue Waves Serial Or ParallelFilters can be chained in serial or parallel mode and scream at high resonance value, which is way quantized into 7 scaled steps.Dms Classic Analogue Waves Series Are 4The 2400 series are 4 channel, 2 of the channels having full attenuators.Dms Classic Analogue Waves Upgrade Resulted InEach upgrade resulted in wider bandwidth and better triggering.
These were still heavy little scopes, and the chassis was complicated and expensive to build. In 1988, prices started at about 2000, and went to 12,000 for the 2467 with MCP CRT, all with 2 to 4 channels. Weight went from a light 3.5 lbs for the diminutive 212 all the way to 24 lbs for the 2467. The early 501 contained advanced circuitry but it was too big and heavy on the bench. That was not enough to compete against the big competitors like Dumont, RCA, Varian, General Electric(). Tektronix realized these drawbacks, and introduced the model 511 (designed by Howard Vollum, Milt Bave and others). The 547 was perhaps the most popular of the large size, valve type oscilloscopes. The 547 was made popular largely because of the innovative ALT mode, which allowed for dual traces to be shown on a single beam oscilloscope, providing much of the functionality of dual-beam scopes for a fraction of the added cost. This was a very expensive approach, as two of everything was required. Tektronix oscilloscopes like this were the 502, 551, 555, and 556. Some of these had two time bases and two sets of horizontal deflection plates, so the horizontal scan of the two beams could be synchronized (triggered) separately from the other. The switch worked to display 2 or 4 separate electrical signals on the screen. This is the technique used in all the dual and four-trace plug-ins such as the CA, 1A1, 1A2, Type M and 1A4. New models available that year were the 2213, 2215, 2335, 2336, and 2337. They offered excellent portability along with light weight and low power consumption. Most of this was due to the simplification of circuit design, and a lightweight switching power supply. ![]() Completely micro-processor driven and firmware controlled, these were a new breed, similar in appearance but not otherwise related to the 2200 scopes. By 1989, the 2465B had 400 MHz bandwidth with triggering beyond 500 MHz. The 2430, the 2432A, the 2465B and the 2467B lasted until 1996. ![]() The 2335 and 2336 are 2 channel, ruggedized versions mostly made for the military.
