NanoScope V Front Panel

The NanoScope V Controller, shown in Figure 1, has the following items on the front panel:

• Controller status LCD.
• Power Supply LEDs (top 3) — indicates the power supply status. These are discussed in System Initialization.
• Diagnostic LED (“active/flashing”) — indicates the FPGA is loaded.
• Connection to the (optional) PicoAngler.
• Connections for Dimension XY, Dimension Hybrid XYZ, Dimension Icon or Dimension FastScan AFM closed loop heads or the BioScope Catalyst microscope.
• Digital I/O BNCs:
  • Inputs (In 1/2) — Pulse counter inputs.
  • Output 1 (Out 1) — End of Line: TTL pulse at the end of each scan line.
  • Output 2 (Out 2) — End of Frame: TTL pulse at the end of each scan frame.
• High Frequency Analog:
  • Lock-In 1/2 Inputs — Analog inputs for two high frequency lock-ins accessible via NanoScope software. The sample rate is 50 MHz giving an effective bandwidth of 1 kHz to 5MHz.
  • DDS 1/2 Outputs — Analog output of the reference signals for two high frequency lock-ins accessible via NanoScope software (1 kHz - 5 MHz).
• Low Frequency Analog
  • Lock-In 3 Input — Analog input for a low frequency lock-in accessible via NanoScope software. The sample rate is 500 kHz giving an effective bandwidth of 5 Hz to 50 kHz. If this lock-in is not used, the BNC connector is available as a third General I/O Input (see below).
  • DDS 3 Output — Analog output of the reference signal for the low frequency lock-in accessible via NanoScope software.
  • General I/O Inputs 1/2 — Analog inputs that can be read as data channels in the NanoScope software. Continuous data collection is done at a sample rate of 100 kHz. “Burst” capture (data collection for a limited duration of time) can be done at a sample rate of 500 kHz via the High Speed Data Capture function in the NanoScope software.
  • General I/O Outputs 1/2 — Analog outputs that can be used to monitor various signals within the controller selectable via Nanoscope software. The update rate is 100 kHz (40 kHz in ramp mode).
