Expert Insights & FAQs

What makes Trueform technology better than standard DDS generators?

Trueform uses a unique sample-and-hold method instead of stair-step DDS. This approach directly reduces aliasing artifacts and jitter. It gives you noticeably cleaner spectral performance and more precise timing, especially for pulses and arbitrary waveforms.

Is the 33511B suitable for power electronics testing?

Yes, its wide amplitude range down to 1 mVpp is useful for driving control circuits. The low-jitter pulses can also accurately simulate PWM gate drive signals. For higher voltages, you will need an external amplifier.

How does the arbitrary waveform sequencing feature help in practice?

Sequencing lets you chain different waveform segments without glitches. For instance, you can create a complex test pattern: a burst of sine, followed by a custom fault transient, then a DC level. This is ideal for stress testing communication or sensor circuits.

Can I upgrade the standard waveform memory later?

The 1 MSa memory is fixed in the standard Keysight 33511B. The 16 MSa option is a factory-installed configuration. You need to specify this enhanced memory requirement at the time of purchase for your specific application.

What's a common pitfall when generating low-amplitude, high-frequency signals?

Impedance matching and cable quality become critical. Even a slight mismatch at 20 MHz can cause standing waves and amplitude inaccuracies. Always use high-quality, properly terminated 50 Ω cables when outputting signals above a few MHz at low voltage levels.
