APSIN20G - 100 kHz up to 26 GHz Signal Generator

The APSIN26G is a low-noise and fast-switching microwave signal generator covering a continuous frequency range from 100 kHz up to 26 GHz. 


  • Advanced technology allows a 0.001 Hz frequency resolution
  • Fast switching
  • Excellent phase noise and a high power output
  • APSIN26G operates with an ultra-stable temperature compensated 100 MHz reference (OCXO) 
  • Can be phase-locked to any external reference from 1 to 250 MHz.


  • High-Performance Lab Generator
  • Automated test systems (ATE)
  • Field measurements

Option B3: Rechargeable Internal Battery Module 
 -With option B3, every APSIN can get internal rechargeable batteries (Ni-MH batteries classified as non-hazardous by IATA; expected lifetime under typical use is 3 to 5 years) that a good for 3 hours of supply-independedent operation. As soon as the APSIN is connected to an external power supply, the batteries will automatically recharge.

The option also adds a grip on the side to make the device easy portable




Option PE/PE2/PE3: Extended Power Range
-With PE, PE2, and PE3 options, the APSIN signal generator is additionally equipped with internal electro-mechanical attenuator that extents the leveled output power levels to -90 dBm to -130 dBm (with overrange to -140 dBm), respectively. The level accuracy is maintained with the help of an internal automatic level control with an integrated power detector.
