The SPM 1000’s multiple inputs and outputs give you immediate access to every signal you need. As opposed to the common breakout box model, these integral connections provide complete signal access with the lowest possible noise. Moreover, all the data that is sent in your controller is as scientifically valid as possible and never filtered or altered without your knowledge. You know exactly how your data is transmitted at every junction, and therefore you know exactly what your results mean. No other SPM company is as forthright and open with its design and engineering. |

- Two 10 MHz pulse-counting input channels for photon (e.g. NSOM) or other digital signals
- 4 user-defined DACs to allow a wide variety of spectroscopic measurements and interface to other laboratory instruments
- 2 Z-position and 2 bias voltage modulation inputs and 1 set point modulation input allow both AC and DC signals to be simultaneously summed for a variety of spectroscopic measurements
- 4 monitor outputs to display data on external oscilloscopes (in addition to built-in software oscilloscope)
- Dual preamp inputs allow either RHK preamp, user-supplied preamplifiers, or lock-in amplifiers
- TTL digital synchronization with external instruments.
- Inputs for integral position sensors to correct non-linearities, distortion, drift, and creep
- DSP scan generator control directly from computer workstation

| Our controller is continuously reexamined to enhance its high stability and low noise performance. Buffered and optically isolated signals, internal groundings, independent power supplies, separately routed DC and AC signals, and custom SPM circuitry all contribute to superior benchmarks. In union with the main SPM 1000 electronics, our specialized preamplifiers have been able to provide a unique combination of low-noise and high-bandwidth operation. In practice, the SPM 1000 has successfully imaged currents down at fragile range of femtoamps. |
