Frequently Asked Questions

Solid Green:  Instrument has finished boot-up up and is ready to connect or operate.

Red: Unable to power up, or re-booting the instrument

Flashing green: Transferring data

To troubleshoot connection issues, first make sure that the Tektronix USB driver is installed. To do this:

Open Device Manager on the PC.  Then look in "Universal Serial Bus Controllers".  You should see your RSAXXX instrument listed like "Tektronix RSA306B".  

If  you do not see your Tektronix RSAXXX listed – you will need to update the USB3.0 drivers from the motherboard manufacturers website.

TekScope Anywhere is no longer available for sale.  It included timing, eye, and jitter analysis using waveform data and setups from Tektronix DPO/MSO5000, DPO7000C, or DPO/MSO70000C/D/DX/SX and waveform data from DPO/MDO3000 and DPO/MDO4000 Series oscilloscopes. The current “TekScope” product supports all functions previously supported by “TekScope Anywhere”.

From a mechanical perspective, there are some differences:

- Sharper tip

- Ground spring attaches directly to the tip without the special sleeve used in the P6139A

- Alligator Ground lead attaches directly above the plastic sleeve and does not use the ground lead with the "donut"

- Sleek design

- Compliant to March 2011 safety updates (UL approved)

Note: P6139A (3.5mm probe tip) and P6139B (3.8mm probe tip) have different diameter probe tips and cannot share probe accessories.

The TPP0100, TPP0101, TPP0200, TPP0201, TPP0500, TPP1000, and P6139B passive probes all share a common probe tip diameter, so the probe accessories work across all of the probes.

A squarewave consists of the fundamental frequency and an infinite number of odd harmonics that rolls off in amplitude at a specific rate. This means that if you have a If you have a 50 MHz squarewave on a AWG2021 the 50 MHz squarewave is well within the 100 MHz bandwidth of the output amp. However, the first harmonic contained in the waveform is at 150 MHz, the next at 250, 350... These harmonics end up being filtered out of the waveform by the limited amplifier bandwidth. The result being that your squarewave looks more and more like a sine wave as you increase the frequency.

Another way to look at how amplifier bandwidth will impact your waveshape is risetime. Take for example a squarewave with 4 points per cycle (2 points high and 2 points low) running with a 250 MHz clock on the AWG2021. This would create a squarewave period of 16 ns with data that is transitioning between 0 and full scale instantly. It would be a perfect squarewave if you had an infinitely fast system to translate that data into a waveform. However in an AWG2021 the rise/fall time is 3.5 ns. This means that 7 of the 16 ns period will be spent between the 10% and 90% points of the waveform or, about 1/2 the time the waveform is transitioning from low to high and back again. While this would still look somewhat like a squarewave, it is certainly less than ideal.

The lower limit is much more cut and dried. You take the lowest available clock rate and divide it by the maximum record length. This method assumes that you create a waveform that is 1 cycle over the maximum record length.

Below is the lower limit and the practical/Nyquist upper limits for each AWG.
