Agilent/ HP 85028A Directivity Verification Standards for 85021A/85027A, APC-7

The Agilent 85028A allows on-site verification of the 40 dB directivity of the Agilent 85021A and 85027A directional bridges. For frequencies below 2 GHz, a precision 52 dB return loss load is used. For frequencies from 2 to 18 GHz, a sliding mismatch is used to establish a ripple pattern from which the directivity can be calculated.

• Includes a precision 50 ohm termination
• Includes a high-performance sliding mismatch
• Includes a 7 mm open/short
• Includes a 7 mm connector gauge kit
• Includes a torque wrench
