Tektronix has released new firmware for the 5 series and 6 series MSO mixed-signal oscilloscopes, and launched a new analysis tool called Spectrum View (spectrum observation). Perform mixed domain analysis on the screen. You only need to update the latest firmware to add this mixed domain function to any 5 or 6 series MSO. Of course, all new instruments will come with this function when they leave the factory.

In order to meet the RF analysis requirements of the high-performance 5 series and 6 series MSO mixed signal oscilloscopes, Tektronix has adopted a new method that does not require a separate RF input channel. Each analog channel of the oscilloscope can provide a spectrum observation function. This latest firmware enables the patented technology built into the oscilloscope to simultaneously view time-domain analog waveforms (bottom left in the figure below) and spectrum observations (right) through the hardware in the instrument, and independently control each domain.

The new firmware upgrade of the 5 series and 6 series MSO can support time-domain analog waveform and spectrum observation at the same time, and can independently control each domain.

Through independent control, you can use the familiar menu method to set the center frequency, bandwidth, and RBW without affecting the time scale in the waveform view. And vice versa, changes in the horizontal scale will not affect the frequency spectrum. Thanks to the independent control function, you can easily correlate frequency domain events with other time domain events.

Independent control allows you to adjust the spectrum in a familiar way.

Both Series 5 and Series 6 MSOs have multiple FlexChannel inputs. Each input can be used as an analog channel or as eight digital channels. Added hardware spectrum observation function, any analog channel can be used to observe time domain waveform and frequency domain spectrum at the same time.

If you connect the TLP058 logic probe to any input, you can enable the digital channels. In other words, any input channel can be used to view time-domain analog waveforms, frequency spectra, or digital waveforms.

The Flex Channel control function means that any input channel can be used to view time-domain analog waveforms, spectrum or digital waveforms.

The following screen shows two channels: Channel 1 tests the output of an 8-bit digital-to-analog converter, which can simultaneously Display time-domain waveforms and spectrum. The input of the channel 2 test DAC is displayed as 8 logic waveforms using the Flex channel.

You can also perform mixed domain analysis on multiple channels, as shown in the figure below. In the analog waveforms of the yellow and blue input channels, each waveform can display the corresponding frequency spectrum. Note that each waveform below is a small rectangular box, which indicates the time point at which the frequency spectrum occurs in the time domain waveform. You can move this spectrum time window in the entire waveform to view the synchronized spectrum at any point in the waveform.

Through spectrum observation, you can also perform mixed domain analysis on more than one channel at the same time.
