 We describe the design and initial test results of the Fermilab vertical cavity test facility (VCTF) diagnostic instrumentation which is used to understand cavity performance, including thermometry to detect hot spots caused by quenches or field emission, and a variable RF input coupler to facilitate the TM010 passband mode measurements used to isolate poorly performing cells.

 Fermilab has constructed a facility for vertical testing of SRF cavities, operating at a nominal temperature of 2K, to be used as part of the global International Linear Collider (ILC) effort to improve cavity processing and performance reproducibility. Following successful cryogenic commissioning, the first tests of single cell and 9-cell ILC-style cavities were performed. These first test results are presented in detail, along with a brief discussion of present measurement accuracy.
