Hewlett Packard 8350 Series
Broadband RF Plug-Ins, Refurbished
Models 83570A, 83572A, and 83572B

• 5 mΩ min. unleveled 26.5-40 GHz output (HP 83572B)
• 10 mΩ internally leveled 18-26.5 GHz output
  (HP 83570A)
• 8350 Series Sweep Oscillator RF Plug-Ins

With high frequency coverage, complete HP-IB programmability and outstanding leveled output power, the HP 83570A or HP 83572A/B plug-ins, combined with the many features of the HP 8350 mainframe add a new dimension to microwave measurements from 18 GHz to 40 GHz.

HP 83570A

Precision measurements from 18 to 26.5 GHz are possible with the solid state HP 83570A plug-in.  This frequency range maintains an accuracy of 30 MHz and a minimum leveled output power of 10 dBm.  Power is internally leveled to a flatness < ± 1.4 dB.  At the output, power losses are minimized with a waveguide output connector (a coaxial output connector may be made using the HP K281C adapter).

HP 83572A/B

The HP 83572A/B RF Plug-in extends the frequency coverage from 26.5 GHz to 40.0 GHz with 100 MHz frequency accuracy. The plug-ins offer minimum unleveled output power of 7 dBm (HP 83572B), and 3 dBm (HP 83572A).   Option 001 provides 6 dBm (HP 83572B), and 2 dBm (HP 83572A) calibrated externally leveled output power for regulated power control during swept and CW operations.

The output power has a calibrated range of 11 dB (7 dB for HP 83572A).  The power level may be manually set to a 0.1 dB resolution, or the power level may be remotely HP-IB programmed to a 0.01 dB resolution.   In addition to a single output power, these plug-ins also have a power sweep function.  This function sweeps the power from one level to another over an 11 dB power range (7 dB for 83572A).  Another important feature that these plug-ins offer is slope compensation.  This compensates for high frequency power losses in external tests by attenuating the power at lower frequencies.

Scalar measurements at high frequencies may be easily made since these plug-ins provide the internal 27.8 kHz modulation (Option 006 on the HP 83572) required for interface with the HP 8756A or the HP 8757A Scalar Network Analyzer in the AC detection mode.  In addition to simplifying the interface circuitry, internal modulation reduces connection losses which are critical at high frequencies.
