You can login to do that! JPG hello anyone have one? It may take a bit to find leaddr perfect example of all 3 units, but it’s worth it i the long run.

Leader Instruments is a top provider of high quality test and analysis solutions and their instruments are utilized by a wide variety of industries. Then again, it can only measure to.

That is strictly an audio instrument. This week I purchased the following: Dec Mon 31, If there leaser any question about the function, refer to the Instruction Manual for correct operation.

Please, do not make maunal copy of the downloaded manual and do not offer to sell it, just use personally to repair defective appliance! Page 2 of 2. This is the section to talk about what to buy and what to do with it.

Have you got a distortion meter and frequency counter yet, or in mind? Refer to page for replacement. Troubleshoot sawtooth generator, log sweep shaper and associated circuit.


Oct Fri 18, 3: Buying a “used” scope. Sawtooth Wave i Output voltage Symmetry i 20Vp. Find all posts by draudio.

Oct Fri 18, 4: Books Support This Site: TTL level output Fan out: It should also be confirmed that the unit connected to the rated power line voltage. A mA fuse is installed on the attenuator pc board T to protect the output from any externally applied voltage.

You can change the level and it will track it, so you can measure the distortion of an amplifier as you increase the ldm-17 power.

It looks almost new. If you want to join us and get repairing help please sign in or sign up by completing a simple electrical test or write your question to the Message board without registration.

I thought I was done The frequency range is 20Hz to 20kHz.

Signal offset is controlled at this point. That way you can measure back tension too. Maybe gain problem in oscillator, a bad cap or two or something else. You need test gear.

BkO of output impedance. Troubleshoot low frequency feedback amplifier and associated circuit for xl and lower ranges. Sawtooth Output – Set: Check all circuit for visual defects such as broken component, loose connection, open wire, poor soldering mamual. Yay I just have all the gear stacked up for now. To avoid electrical shock, do not perform any service in this manual unless qualified to do so. Oct Thu 17, I really like Leader test equipment and use their FM stereo generator. You really want a dual channel so you don’t have to constantly go back and forth switching test leads or remember what the reading was for one channel so you can look at the other channel.


And east is east and west is west, and if you take cranberries and stew them like applesauce, they taste much more like prunes than rhubarb does. I can’t wait to dig in and start learning how to adjust the decks. I think you are pretty well set for test gear. For this to be meaningful, the RF into the receiver must be modulated with a clean sinewave. Leader Instruments employs rigorous testing at every stage of production and their commitment to quality is evident in every piece of equipment that lcm-171 manufacture.

Right now I have a stack of equipment I do not know how to use yet.

I suppose I need a short list of “what to buy” for those 2 pieces of equipment also. Hello, I was just curious When connecting the oscilloscope to the test point, use a low capacitance probe.

I’ll be on the lookout for a dual channel LMVA as well. Oct Fri 18, 1: I must say the bomb proof case is a nice touch. Most of the other distortion analyzers out there are not auto leveling, you have to null out the original frequency leder set the level.
