This chapter provides details and procedures for calibrating the MS2085A/89A Site Master in VNA mode.
Note
For accurate results, the instrument must be calibrated before making any measurements.
The Site Master is a high-precision instrument. When making 1-port or 2-port measurements, the instrument must be calibrated in order to remove residual errors due to measurement setup conditions. Anritsu recommends performing the calibration under the same conditions as the measurement: temperature, frequency, number of points, source power, and IFBW. The calibration must be conducted using the appropriate standards at the open end of any test port cables and adapters that are connected to Port 1 or Port 2 of the instrument. This will ensure that the match, phase length, and loss of these cables and adapters are all accounted for. For optimal performance, high quality phase-stable cables and precision adapters must be used.
