SMA calibration kit - Kirkby Microwave 85033.

This SMA calibration kit is suitable for all Agilent, HP, Anritsu, Copper Mountain, LA Techniques, Rohde & Schwarz, Picotech, National Instruments, Tektronix, Siglent, LibreVNA and SDR-kits VNAs. It should also worth with other VNAs, but please contact us about others before buying from our website. Sometimes SMA calibration kits are referred to as SMA cal kits. The 85033 is really an SMA calibration and verification kit, as an attenuator included with the kit allows the calibration to be verified. However, the name SMA calibration kit is used, to be consistent with industry practice.

The kit is available in versions from 7 to 20 GHz, with the 7 GHz being the cheapest, and the 20 GHz being the most expensive. Kits for 7, 8, 9, 10, 11 and 12 GHz each use especially selected SMA loads. The 20 GHz kit uses 2.92 mm loads, which adds significantly to the cost.

Most options may be added to the kit after the initial purchase, as the foam insert is cut with space for several options. However, if you require a set of 3 phase-matched adapters, which are highly recommended for the HP/Agilent 8753, 8719, 8720 and 8722 series VNAs, it is suggested that you purchase these with the kit (option 003E), rather than purchase the adapters at a later date (option 003F). This is because the option changes two of the adapters in the kit for different models, so it costs us less to include this option with the kit.

Introduction to the 85033 SMA calibration and verification kit

The 85033 SMA calibration kit is suitable for calibrating all HP, Agilent, Keysight, Anritsu, Rohde & Schwarz and Copper Mountain vector network analyzers. As well as the leading manufacturers of VNAs listed, the kit can be used to calibrate virtually any vector network analyzer to enable SMA, 3.5 mm or 2.92 mm coaxial devices to be measured, irrespective of the test ports on the VNA (N, 3.5 mm, APC7, 2.4 mm etc). In addition to the leading manufacturers of VNAs, the kit has been used with VNAs from Picotech, Siglent, LibreVNA, National Instruments, LA Techniques and SDR-kits. The kit includes parts for both male and female genders, so it is not restricted to male or female components only as some VNA calibration kits are male SMA calibration kit or female SMA calibration kit available from other manufacturers.

The maximum frequency range of the SMA coaxial calibration kit can be chosen to be 7, 8, 9, 10, 11, 12 or 20 GHz, with 7 GHz being the cheapest, and 20 GHz the most expensive. The kit is both a calibration and a verification kit since is supplied with an attenuator which can be used to verify the calibration is correct. The S-parameters of the attenuator was measured on an HP 8720D (20 GHz) VNA using an Agilent 85052B 26.5 GHz 3.5 mm calibration kit. After setting up the VNA to use the calibration kit, calibrating the VNA, the user can check the VNA is performing correctly by measuring the attenuator which is provided and comparing that to the measured results, which are on a USB stick supplied with the kit.

Options to improve functionality or performance

The standard 85033 SMA kit includes all the components necessary for a VNA calibration kit. However, the following options are available to increase performance and or functionality. (A torque wrench is essential, and is option 004 if you don't have one).:

The standard VNA calibration kit for SMA connectors, which includes an attenuator for verification purposes, has the following properties:

Purchasing the 85033 SMA calibration and verification kit

The SMA calibration kit may be purchased in several ways. The prices vary somewhat depending on where bought, the method of payment, the currency, due to the commission charged by various bodies (banks, Paypal, eBay etc). If people want a proforma invoice or formal quotation, let us know, and we will produce one.
