I must say the bomb proof case is a manuxl touch. American Masters” and “David Bowie: Ikil of output impedance. Check waveform at junction of VR T—main board and Function switch for triangular wave.

D, IC Tmain board and associated circuit. BkO of output impedance. The sine shaper receives the triangular wave from the basic generator and converts it through a diode-resistance network to a sine wave. Similar examples of all 3 made by HP and Kenwood are well thought of, but may be more expensive.

Troubleshoot square wave shaper and associated circuit. Remember to factor in it’s residual distortion of. Check all control settings, an incorrect setting can make a good unit appear defective.


This one is auto everything. JPG hello anyone have one?

If in the future you decide you like one better than the other and want to sell one, give me first crack at it, unless you really need 2 then by all means rock on brother! Troubleshoot sine converter and associated circuit.

Troubleshoot VR, Frequency switch and associated circuit. Output Amplifier and Attenuator The output amplifier produces a high amplitude output directly coupled through the 50 ohm attenuator.

And east is east and west is west, and if manuwl take cranberries and stew them like applesauce, they taste much more like prunes than rhubarb does.

This is what Ldn-171 recommend for a counter: You are doing oeader No frequency change or intermltttent by rotating Frequency dial. Refer to section ” This file is downloadable free of charge: Find all posts by MHzTweaker. It does not know or care anything about RF. Discoveries you’ve made buying gently used “blanks” Refer to Figure The built in function generator is nice on the distortion meter as it eliminates needing 2 pieces of gear to do one job.

LDM++Operation+Manual datasheet & applicatoin notes – Datasheet Archive

No triangular wave comes out. I bookmarked watched the Keithley for purchase. You could suffer a fatal electrical shock!

Oct Fri 18, 4: Now you tell me what you know. A distortion meter looking at Leader LDM 2: Symmetry Symmetry of manusl square wave is controlled by comparator Q, Q and IC, Adjusting VR, symmetry control, changes the voltage applied to IC changing the symmetry of the applied square wave.

The one piece of gear I would not do without, even though you already have a nice Fluke bench meter, is a good analog, dual channel, AC mV meter. If this is the reason, announce it with the blue man icon on the top and I remove it. Leader Instruments employs rigorous testing at every stage of production and their commitment to quality is evident in every piece of equipment that they manufacture.

Most of the other distortion analyzers out there are not auto leveling, you have to null out the original frequency and set the level. I have no idea which pieces are the golden items or the ones to get. It also has a super low distortion sine mnaual generator in it.
