Siglent F505MS 18 GHz N-M type VNA calibration kit
Mechanical OSLT calibration kit for vector network analysers: open, short, load and through standards in N-type male, specified from DC to 18 GHz into 50 Ω.
N-type male, DC – 18 GHz
The F505MS is a a mechanical OSLT calibration kit: open, short, load and through standards in N-type male, specified from DC to 18 GHz into 50 Ω.
A vector network analyser does not measure your device — it measures everything between its own receivers and your device, including the cables you fitted and every connector in between. Calibration is how that gets removed. You present standards whose behaviour is known precisely, the analyser measures them, and it then solves for the errors in the path. The reference plane moves from inside the instrument to the end of your cable, which is where your device actually starts.
Discrete standards. The open, short, load and through arrive as separate precision pieces. It is the classic arrangement and the lower-cost one; the Y-series kits hold the same standards in a single integrated body.

Gender matters
This kit is male only, so it mates with female interfaces. If your two ports need different genders, the F505TS supplies both in one box.

Connector, gender and frequency are Siglent’s own, from the price list and the SNA5000A, SNA6000A and SNA5000X-E ordering tables. Siglent does not publish per-kit residual figures such as directivity or load match — if your application depends on them, ask us and we will request them from the factory.
Worth checking before you order
Every Type-N vector network analyser in the Siglent range tops out at 9 GHz, so no instrument we sell needs an 18 GHz N kit to calibrate itself. This kit is for N-terminated work on a higher-frequency instrument, or for an N-port analyser from another manufacturer. If you were looking for the kit for a Siglent VNA, the F504TS at 9 GHz is almost certainly the one you want — ask us and we will confirm.
Other kits in the range
All twenty-one mechanical kits, with a table matching every Siglent analyser to the kit it needs, are on the VNA mechanical calibration kits page. Electronic calibration is covered on the calibration kits overview.
Not sure this is the right kit?
Three things decide it: your analyser’s test-port connector, your top frequency, and the gender of the cables you calibrate to. Tell us the model and we will confirm which kit fits before you order — and whether an ECal module would serve you better.
