VDI Millimeter-Wave Frequency Extension Modules for PXA, MXA, EXA Signal Analyzers
These modules offer low conversion loss and excellent noise figure. Standard features include dual operating modes. First, the module can function as a high performance down-converting mixer. The second operating mode functions as a block down-converter with a broadband IF up to 20 GHz. Power to the module is provided via an included external DC power supply. These frequency extenders minimize conversion loss by multiplying and amplifying the LO signal internally, thus taking advantage of the benefits of low harmonic mixing. This architecture also preserves the X-Series precision frequency resolution and low phase noise, extending those qualities into the millimeter and sub-millimeter bands.

Test Fixture, Shielding Effectiveness
EM-2108 | 1.5 GHz – 10 GHz
The EM-2108 is a standard test fixture for evaluation of the electromagnetic shielding effectiveness (SE) of planar materials. The fixture is a section of coaxial transmission line broken to allow the insertion of planar test materials. Although ASTM D4935-10 is currently limited to an upper frequency of 1.5 GHz, the EM-2108 meets and complies fully with both the impedance and SE requirements called out in ASTM test method D4935-10 up to 10 GHz. These results are shown in Figures 1 & 2. The measured data relates to the shielding effectiveness due to a plane wave (far field EM wave) from which near field values for magnetic and electric fields may be inferred.

Biconical Antennas
For many years most standards called for the use of a half-wave dipole antenna set for frequencies above 80 MHz. However, to reduce test time, broadband antennas such as the biconical antenna and log periodic antennas began to be accepted. Broadband antennas, compared to half wave dipoles, reduce test time because the technician did not have to stop the test to adjust the dipole antenna for each frequency. A.H. Systems'' 7 models of Biconical Antennas operate efficiently over the frequency range of 20 MHz to 18 GHz. Suitable for FCC, MIL-STD, VDE, TEMPEST, and immunity testing, each Biconical antenna will provide reliable, repeatable measurements.
