Data acquisition is done in abundance with the SPM 1000 and XPMPro software. 10 channels of input data provide an incomparable amount of data variety. Auxiliary channels can measure any type of voltage data, such as friction, thermal data, a lock-in amplifier signal, BEEM, MFM, etc., in addition to the dedicated channels for topography and current (force in AFM). In addition to this, each channel records both the forward and reverse scan directions, which is especially useful for evaluating piezo distortions and scanning artifacts.
XPMPro is a next-generation software program with advanced configurability, an attractive interface, plentiful tools, an ergonomic layout, and a burgeoning feature set. All 10 channels of data can be imaged simultaneously during real-time acquisition, and a multichannel line chart provides the same acquisition data in the form of a real-time plotted readout.

| The acquisition screenshot of an integrated circuit shows off XPMPro’s data acquisition versatility. Because each signal will have its own characteristics and contrast ranges needs, all 10 acquisition windows are individually customizable even while acquiring data. Acquisition parameters, such as bias and set point, can also be modified during acquisition to observe their real-time effects. XPMPro stores each window’s unique color mapping and filter settings, along with all other acquisition parameters, in user preference files. |

- XPMPro leads the industry in data density by imaging at up to 8192 x 8192 pixels.
- A 2.0 MHz high-speed acquisition module is available for maximum scan speeds. Scan an area of 128 square pixels in a record-breaking 1/20 second.
- XPMPro records all your channel data as often as once per pixel or once per frame, digitally archiving instrumental records (magnetic field, pressure, gas flow, etc.) that no

The SPM 1000 has built much of its reputation on the specialized ability to perform advanced spectroscopy. A masterful array of parameters, techniques, and automations give XPMPro the most sophisticated and flexible spectroscopic acquisition available. In software, you can control timings such as pre-sample delays, sample count, sample rate, sweep rate, and, of course, the step increment. Higher-level parameters are also configurable, such as stabilization intervals and pre-spectrum delays. With the ability to ramp any two voltages (bias, Z, set point, light intensity, frequency, etc.), and the power to use feature tracking for point spectroscopy, the research potential is limitless. |

The three dynamic parameter functions of SPM 1000 are the pre-programmed solution to research across variable conditions. Multiple Parameter Imaging (MPI) and Automatic Parameter Imaging (API) repeatedly scan over the same space while varying some chosen condition. MPI is adept with time-sensitive surfaces and in situations of high drift, since it scans and varies conditions line by line, instead of frame by frame. This gives scientifically valid results when conditions are volatile or in motion. API, meanwhile, is a dynamic parameter workhorse. It has the potential to increment a chosen condition over 65,536 separate frames. Working unattended over days, API can provide volumes of precisely coordinated experimental data. |
| The last function, Dynamic Playback, passes over the same scanned line while replaying previously acquired channel information, allowing signals such as magnetic or electrical forces to be deconvolved. |
