PERFORMANCE VERIFICATION
XFVP probes are shipped from Saker and both probe head and receiver are tested as a system
and adjusted to meet the DC gain, offset and frequency specifications. Accuracy is
automatically maintained by two internal precision voltage references and a software algorithm
so there is no provision for manual user adjustment. If the probe fails repeatedly to calibrate
with a properly terminated scope, it must be returned to Saker for inspection. The
recommended calibration interval for the model XFVP is two years.
Equipments needed to perform verification:
-
Bench Multimeter of at least 5.5 digits, AC and DC accuracy better than 0.1% (Keysight
34450A or similar)
-
Adjustable power supply or precision voltage source
-
Banana to BNC cable (Pomona 4531 or similar)
-
BNC-SMB adapter (Amphenol 242185 or similar)
-
BNC-BNC cable (Caltest CT2942 or similar)
-
50 Ohm terminator (Pomona 3285 and Amphenol 202104)
-
BNC to banana Jack adapter (Caltest CT2939 or similar)
Functional check
The functional check verifies the basic operation of the probe functions:
-
Turn on both emitter and receiver.
