Re: MDO3014/54 with Every Option Plus Some

Well, with his listing prior to updating his firmware there were some extra options. Why doesn't my MDO list them as possible options: MDO3AUTOMAX, MDO3ENET, MDO3VID, MDO3USB, and MDO3TRIG? Are these actually available? cap

OK, It's been a couple of years, and I can barely follow scripting, and then only somewhat... Assuming you have a 784A, others very simular. Below is a list of the cal procedures you need to accomplish to fully calibrate your scope. Notice the addresses, when you start the "cvr_cal", that section ch...

MDO3014/54 with Every Option Plus Some

Check out ebay item: 272026408102.

I wonder if it would all persist with the current firmware.

Re: TDS754D not booting anymore

You may need to install a new chip. It's a multi-layer board, you might want to add solder to the tops side of the board hoping that it will help wet an inner layer that just isn't quite making a good connection, lots of flux. Otherwise, check for continuity from each pin to the board somewhere (oth...

Reheat the nvram solder pads/load them with solder. This has worked for me in the past. cap

Re: TDS5000 series - Error Codes 332

332 Acquisition: Acq Modes:PeakDetect, Tests the four ADG439's while in peak detect mode. Has to do with decimation, having never dealt with this, I would observe a signal on all four channels in this mode and see if one channel stands out. cap

Re: TDS 784 Calibration problem (Voltage Reference)

The probe adjustment cable is just a bnc cable with Y-leads at the end. Make sure ground is to ground or it will fail, be prepared to do a bit of math; you'll need to use a dmm. This is a more involved adjustment then on a TDS600, start with channel 2, then 1,2,3, and 4. To pass, you do need to do t...

Re: TDS 694C doesn't boot

Just some guessing… I’ve had scopes (all this family) that had trouble booting (one problem) AND the front power switch contact pad is all but warn out with people trying to get it to power on (another problem). If someone has ever removed the front panel, it is easy to damage the flex panel cabling...

Re: TDS 7104 Tekscope.exe doesn't start up

It can be a couple of things but usually it has something to do with the battery on the powerpc board, unplugged temporarily or dead. There is a console port on the right side of the scope that you need to tap into (if your lucky their'll be a cut out in the aluminum and only a side cover will need ...

Re: TDS 7104 Network Boot

Hello, It's been a while but I've had several TDS7104's and none of what you describe is bad. The first step is to get your scope to boot to windows, and who knows, it may then fully boot up as an oscilloscope. The windows portion of the scope is what the service manual refers to as the NLX board. F...

Re: Advice on diagnosing 2nd channel failure

Read the extensive threads on electrolytic capacitor issues on the TDS500/600's, as your scope is from the same era (basically scrub the boards clean, replace the caps, hope it powers on fine; if not, probably an open somewhere). Once you feel that you have addressed capacitor issues, you can compar...

Re: TDS3054B horizontal timebase jumps all over the place

I think these are similar to the later dpo's, 2 forks of different lengths that brush along encoder strips (pc board traces); these make and break connections and determine speed and direction of rotation. If dirty or more commonly the knob gets whacked the shaft will now have some play and the oper...

Re: TDS 2012B power supply repair

A new power supply would be an easy fix, but before ordering do this. On the acquisition board find the small four channel tantalum capacitors, usually yellow in color but there may be black ones (these are usually inductors on tek boards). Now, under 8X or so magnification, verify that there are no...

Re: TBS100B series noise spec

I would look on youtube for TBS1000B scope videos and try to compare your scope with those. You can also open a formal service request with tek to ease you mind that your scope is or is not functioning correctly. In all vertical settings there will be some vertical noise, not a perfectly flat line, ...

Re: TDS 540 Not Booting

Lets see, the TDS520B component service manual does talk about the DS1 display codes, if you want to dig into that. This scope probably has a front firm face card, but since your seeing numbers on DS1, that is probably present though you should check the part number to see if it is the correct part ...

Re: Tektronix DPO4034 and DPO4BND application module

... "MDO/MSO/DPO4000B and MDO4000 Series". Is your scope a DPO4034 or DPO4034B? If its a non-B then your probably out of luck, but I would verify with Tek to be certain. cap

Hi Strick, I have no experience with your scopes so unless someone else chimes in, you will need to become the expert here. With the TDS 5/6/7 scopes the spc had to pass or the cal software would not let you proceed and actually calibrate the scope. May not be the same with your scopes but keep in m...
