I have tried out the Scope Clock on a couple of different oscilloscopes.
Tektronix 604 Monitor.
The Tek 604 Monitor is a X-Y monitor with intensity control on the Z input. It has a flat and sharp screen. Funny thing about the 604 is that it has no fan and no power indicator and you will not display much if you don’t get the signals right. So when i first powered it up i thought it was broken. Like many Tek machines of this era it is well built and engineered.
Tektronix 465 Oscilloscope
The Tektronix 465 is a single beam, dual channel 100 MHz Oscilloscope. Mine wat built around 1973. Everything on the 465 makes it clear this machine is from a different time. The controls are sturdy, the illumination are little light bulbs and not LEDs. The scope is not just electronically complicated but also has many mechanical parts just to put the actual switches in the best spot in the signal path and put the control of the switch on a logical place on the front panel. The schematics are hand drawn. The X-Y mode is a position on the timebase.
The Fluke PM3092 is a dual beam, 4 channel, 200 MHz analog scope with digital control. It has the disadvantages of an analog scope combined with the confusing controls of a modern scope. The Fluke and I are not good friends. The X-Y mode is hidden in “TB-mode”, soft-menu “X-DEFL” off, channel 1 off.
HP 546xx series Oscilloscopes.
The HP 54602B and 54622D are digitising oscilloscopes, basically a computer with fast AD converters. The display is a monochrome CRT. The controls are well designed and present an interface that is easy to understand for both traditional analog scope users and users more used to digital systems. These were built around 1996. The X-Y mode can be set by pressing “Main / Delayed” and then the softmenu “X-Y”.
The BCR2000 is a midi controller from Behringer . You can use it to modify midi parameters with pushbuttons and rotary knobs.
The BCR2000 is not really expensive (current price (Sept 2010) is 139,- euro from feedback). It has a few minor drawbacks like the infamous “wobbly knobs”.
All rotary encoders have a string of leds as indicators. I had expected Behringer would have used prefab modules with switch and LEDs for this from Bourns or Avago and was surprised to see this was not the case. All rotary knob and led parts are built up from separate parts. The BCR2000 consists of an amazing number of parts.
The BCR2000 has a swichmode power supply an d 3 other PCB-s.
6 x HC574 “Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs”
4 x HC273 “Octal D-Type Flip-Flops With Clear”
6 x HC163 “4-Bit Synchronous Binary Counters”
1 x HC138 “3-Line To 8-Line Decoders/Demultiplexers”
1 x PDF OKI L671000: An ARM7TDMI CPU with full speed USB and UART, handy for MIDI.
1 x TMS 418160DZ, a 2 MB DRAM. The CPU apparently has DRAM Refresh logic on board.
1 x HCT04 “Hex Inverters”
1 x H11L1 “6-Pin DIP Schmitt Trigger Output Optocoupler” for the receiving side of the MIDI current loop.
1 x HCT245 “Octal Bus Transceivers With 3-State Outputs”
The Philips Living Colors is a remote controlled 15 W. RGB led lamp.
It is available (April 2008) in the UK, The Netherlands, Belgium, France and Luxemburg for about 110 to 150 euro.
The build and design are high quality. This is not a re-labelled generic chinese designed product.
The remote uses a radio frequency transmitter and reciever om the 2.4 GHz ISM band from Chipcon (now Texas Instruments). It does not need line of sight and can control up to 6 lamps independently or as a group.
The microcontroller in the remote and lamp is a low power microcontroller from Texas Instruments. The comminication is bi-directional which suggests Philips has more products planned, say an AmbiLight – LivingColors bridge.
