The Agilent HP 8753ES RF Vector Network Analyzer features a built-in 50-ohm or 75-ohm S-parameter test set providing a full range of magnitude and phase measurements. Full two-port error correction capability provides the highest level of accuracy and the S-parameter test set provides the convenience of making both forward and reverse sweep measurements without reversing the device under test. Frequency range is 30kHz to 3GHz with a 1Hz resolution.
Note - Option 011 deletes the built-in S-Parameter test set.
This allows the flexibility to be paired with either the 85046A for 50 Ohm measurements, or the 85047A for 75 ohm measurements. It's also possible to use with ATN-4111A S-Parameter Test Set (HP N4113A)
