Re: Can AFG3022B generate square wave with different off time?

Yes, this can be done a couple of ways. Using a single channel, you an load a custom ARB waveform that has this pattern and play it. Using both channels, you can setup the 8s pulse on CH1 and then put it in Burst Mode (1 cycle) with external trigger, and then use CH2 to create a square wave with an ...

Re: Old equipment question

A curve tracer is a relatively specialized piece of gear that is designed to characterize the DC parameters/properties of devices such as diodes and transistors. While they're not made by any major manufacturers anymore, they are fairly highly sought after by both collectors as well as certain compa...

Re: DPO7254 serial bus decoding

Unfortunately, the changes to the DPO7000C platform (64 bit win 7) were too extensive to offer an upgrade kit. At the time that the 7000C was introduced, Tek offered a generous trade-in program to swap a 7000 for a 7000C + some $. Of course, that was about 9 years ago.

Re: DPO7254 serial bus decoding

I had to check with one of my time-domain colleagues (I'm more of the RF guy), and he said: DPO7000 Can trigger on I2C/SPI/RS232,CAN buses Can decode NRZ data ( high speed serial such as PCI Express) with option "PTD" Can decode CAN & LIN bus with option CAN But I don’t think we ever did on-screen d...

What version of firmware are you running? The latest that was available for that scope is v5.3.5, available here:

Re: MDO4054C: SPI bus event table?

Double check your bus setup and the threshold settings for the SS line. You can see the start of frame which is the green [ symbol, but the end of frame should show up as a red ] symbol. This is not shown with makes me think that maybe the threshold isn't set correctly. tek00000.png tek00001.png

If the scope and probe are working properly, you should be able to trigger on the current measured by the current probe.

Re: Measuring Burst Frequency

You can turn on averaging in the Acquire menu, that will help. Also, make sure that the sample rate is sufficiently high (increase record length if necessary under the Acquire menu). Also, make sure the peak-peak of the signal occupies 80% or more of the vertical display.

Re: Measuring Burst Frequency

Setup the scope with the Trigger Mode set to Normal, adjust the Holdoff to 10ms. This will ensure that the scope triggers on the beginning of the 10-cycle 10kHz burst. Set the scope to 200us/div and adjust the horizontal position so that you see your complete burst. To measure the 10kHz carrier - tu...

It does sound like your friend may have fatally damaged the scope, likely the Tektronix custom digitizer ASIC. Have you run a self test on it?

Re: RSA306B EMCVu RBW issue

I found out from engineering that the CISPR 16.1 standard has a limit on Band C (30MHz to 1GHz) for the 6dB RBW range of 100k to 500k. Therefore, this limit was put into EMCVu.

I am sorry, but the optimizations to the IF stages under these conditions is not something that can be bypassed by the user.

Re: RSA306 CISPR AVG and CISPR QPk detector issues on EMCVu

Without speaking to the system architect, I am fairly certain that this is due to the fact that only the CISPR Avg and CISPR QPk require the 5MHz acquisition BW processing, while the others all use the 40MHz acquisition BW. At the narrower BW, further optimizations are done in the IF stages to give ...

I was able to change it to 1MHz (see attached). There may be something else in your setup that is limiting this. Can you attach a EMCVu project setup file .emcsetup? (Setup Wizard > Save Project Setup)
