Revolutionary Flexibility

The Siesta amplifier provides 32 channels for data collection: any physiological signal may be recorded on any channel:

• Differential or Referential
• True 16 bit resolution
• Sampling rates to 1024Hz
• Two expansion ports for accessory modules; oximeter, pressure transducers, event button….interface up to 32 additional signals

Revolutionary Power

• Use standard alkaline A cells…OR
• Use rechargeable NiMH battery pack (Recharger built in – recharge Siesta just like you charge your cell phone)…OR
• Run Siesta on AC power; just plug it in

Revolutionary Wireless Data Transmission

Siesta’s ethernet radio link provides the researcher with testing options and opportunities never before available. Your subjects are free to move about while you continue to monitor and collect data. Set up a testing room in just minutes. Use Siesta in your movement lab or as your best solution for recording outdoor. The Siesta802a is compatible with all current 802.11 wireless network standards, including the 2.4GHz and 5 GHz bands.With proper configuration, the Siesta System works with most wireless network infrastructures commonly in place in hospitals. Compumedics also provides a line of Access Point Modules. The Siesta System supports WEP (40 and 128-bit), WPA1-PSK and WPA2-PSK security standards.
