Yet again time is hurtling away at FTL speeds, its nearly September for crying out loud, the workshop & sales have been busy over the summer (lol) months plus I'm working on some interesting new projects: One IoT wearable medical tech plus some new 5/6G communication devices which do require quite significant investment to enable you to obtain accurate. repeatable high bandwidth abilities IE over 25Ghz .

Have restored some really nice older equipment recently including a rather nice Akai 2350 (which in fairness looks like it had just left the factory before we had the privilege of working on it) who says you need gazillons of watts to sound good!

More lab updates and internal restructuring, new to chez Coherent towers a really neat time saving piece of test equipment a Keysight N6705C DC power analyser which is in effect four instruments in one neat package an DVM digital volt meter / Arbitrary wave form generator this allows you to design your own wave forms to simulate various load/ start up and power draw changes within a devices power/ load state change and power down cycles / Data logging which allows you to monitor the device under test performance over a given time period then go back and analyser the data at a later time very handy for references / Oscilloscope mode which allows wave form visual read out in the time Vs voltage domain. The device has four modular slots which allows up to 4 individual power supplies to be fitted, or DC electronic load modules as well. It can even accommodate a SMU (source / measure unit which can source and sink current in one module) so really 6 instruments. Images to follow next week once I've install a wraparound curved 34inch 4K monitor and rejigged the main lab bench (again)

As mentioned before due to the upcoming projects it has been necessary to bite the bullet; so I have been negotiating for one these measurement power houses, as I'm fresh out of kidneys and like to keep my sound system (lol) robbing banks these days is a bit old hat, seems that digital white collar crime is in vogue (lol) not that I wouldn't know WTF to start

Anway in the not-too-distant future one of these world class signal analysers’ will be finding its way to the lab, have measured up and worked out its location (lol) not much I can't dig out of the so-called digital mud with this wee beastie.

Ok, inbetween the bouts of soldering iron twirling, diagnostic work and large amplifier disection I finially managed to fit the new power & sink modules to my new bench toy. Slight issue is that the DC load can handle 40 amps and the front panel bindings are 'only' rated for 20 amps so I fabicated a new dual loom that exits from the rear of the analyser plus a pair of sense wire (fully sheilded) for extra precision measurements.

Also got to try out the new Pathwave power analyser software, it's rather natty including a scope view/datalogger and arb generator for designing ramp up on / down waveforms for testing swicth on and on's currents etc.

This is going to save a lot of timing when designs power/communications and IoT circuits in the comming months.

Below I am testing out a power supply for a LB clock, note the four wire sense connections for utimate accuarcy. Second image is of the data logger.

Perhaps they should rename The WaveMonster

For me its 320 Billion samples a second that is more desirable utter BS free asbolute accuaracy

That'll fill up the storage awful quick.

yeah but, .. how does it sound?  

Brilliant
It's black !

Unfortunately I have hit the ceiling with the new one earlier this year, however its a wee bit more than a PC to be fair.

Motorbike scissor lift; clever.
