My laboratory I

Some are curious about my lab tools.

Well, I do have some stuff collected in years.
The most important tools in a electronics laboratory are the scope and the signal generator.
My scope is a AGILENT DSO 1014A, a four channel 100 MHz 2GSa/s scope. I wish it was a analog one but they are very big and expensive. Why my wish? Because you can use it on some measurements where a digital scope is useless due to alias issues.
This scope is a nice one but, in reality, is made by RIGOL :-) Either way, it's a nice piece of equipment!

Agilent's DSO1000A Series oscilloscopes deliver the performance and features you'd expect in a big scope - and the portability and low price you require in a small one. They've redefined the economy scope by giving you more: more signal viewing, more capabilities and more productivity.

Description from Agilent webpage:
Capture long time periods with high resolution
All models provide provide up to 20 kpts per channel of convenient acquisition memory standard. The scope will maintain high-resolution acquisitions even at slower timebase settings so you can see the details on your signals.
See your signals more clearly
The DSO1000A Series incorporates a bright, crisp LCD color display. You can quickly view your signal from almost any angle. Unlike conventional scopes that always require menus to be on, the entire 5.7-inch diagonal screen is available for waveform display as needed.
True Zoom mode for signal details and context
Dual display and True Zoom shows your entire signal and zoomed in waveform details at the same time.
23 automatic measurements
All DSO1000 Series scopes come equipped with 23 automatic voltage, time and frequency measurements. Press the Measure key to bring up the three you use most often or display all single-channel measurements on the screen simultaneously.
Sequence mode for easier debug
Record up to 1000 occurrences of a trigger event and then play them back to easily spot glitches or other anomalies for further examination. Store the waveforms to internal or external memory (USB flash drive).
Digital filtering on waveforms
Apply a real-time digital filter of your choice to the source waveform to eliminate unwanted frequencies from your display. Digital filtering selections include low-pass, high-pass, bandpass and band-reject filters. Frequency limits are selectable between 250 Hz and the full bandwidth of your oscilloscope.
Advanced triggering
Triggering options for the DSO1000A Series include edge, pulse width, composite video, pattern and alternate channel trigger modes. These modes ensure that you can capture and view hard-to find signal conditions.
Make fast go/no-go decisions
Automatic pass/fail mask testing comes as a standard feature on all 1000 Series scopes. Acquire a "golden" waveform and define tolerance limits to create a test envelope. Incoming signals will be compared to the allowable range and quickly flagged as pass or fail. This is ideal for manufacturing or service where you need to make decisions quickly.
Waveform math and FFT
Standard math functions include addition, subtraction or multiplication of any two input channels and Fast Fourier Transform (FFT) with four user-selectable windows (Rectangle, Hanning, Hamming and Blackman).
Programming and Connectivity
For remote instrument control over USB, use Agilent's I/O library or National Instrument drivers in your application. The drivers are compatible with Agilent VEE Pro, National Instrument's LabView and LabWindows/CVI.
Built-in USB host and device ports and free IntuiLink software make documentation and PC connectivity easy. Store waveforms and setups to a USB flash drive, easily update scope firmware and print to any PictBridge compatible printer.

Here is a flash movie, pretty self explanatory:

Personal, I like the Zoom function, the Sequence and the Save/Recall.

The signal generator is a ZOPAN KZ1405 Function Generator  produced in the 80's by the Polish Institute and Scientific Equipment Manufacturing -Zopan.
It covers 0,01 Hz - 10 MHz in square, triangle and sinus waveform. It's a well built analogic signal generator and it works very nice. Only a little contact spray to the potentiometers...
Has sinusoidal, triangle and square wave forms, all of them with variable ratio (they call it "symmetry") and a very usefull offset setting!

Very, but very simple and reliable!
I will change the capacitors when I will have some time because I suspect that some distorsion at 0-10 MHz due to ageing.

Some guys thinks the KZ's are adequate for making music... Well, I don't!

Thanks to a great Polish guy, I do have the schematics for my Function generator!  Niiiiiceeeeee!
