Keysight Technologies S93089B

The S93089B combines source-phase control of multiple internal or external sources with frequency-offset mode, enabling simplified test of I/Q modulators/converters and differential mixers, and harmonic measurements of differential amplifiers. The phase difference between sources can be fixed (for example, at 90 or 180 degrees), or swept between two specified phase values. Providing accurate control of the relative phase between sources eliminates the need for hybrid couplers and baluns to create quadrature or differential signals. 

After achieving the desired phase alignment, the instrument's receivers can be tuned to all frequencies needed to characterize the DUT. On an I/Q modulator for example, measurements can be made of both the desired and suppressed conversion bands, along with LO leakage, harmonics and other spurious signals. Phase sweeps can be used to determine a DUT’s phase imbalance versus frequency. 

Users can specify measurements with individual receivers or multiple receivers combined with a wide range of mathematical operators. Power measurements can employ match correction for increased accuracy.

The S93089B is equivalent to Option 089 on the PNA Series A models and only works on 4-port PNA or PNA-X models.

Note:

¹ Supported software license types: fixed-perpetual (1FP), transportable-perpetual (1TP), fixed-1-year (1FY), and transportable1-year (1TY) (note: S93093B, S93094B, S93898B, and S94510B have fixed-license types only).

² For N522xB and N5241/42/49B, vector-noise-corrected measurements require an ECal for use as an impedance tuner. For N5244/45/47B with Option 029, an internal tuner is included. Noise calibration requires a power meter when using a standard receiver. When using the low-noise receiver (Option 029), either a power meter or a 346-series noise source is required (Keysight 346C or 346C-K01 recommended). A power meter is required for measuring mixers and converters.

³ A configurable test set is required for VMC measurements to connect a reference mixer, or for SMC+Phase measurements using the comb-generator-based calibration. When ordered with PNA test set Options 200, 210, 400, or 410 (no front-panel jumpers), phase and delay measurements can only by done using SMC+Phase with a calibration mixer.

⁴ S93087B can be used without PNA-X Options 22x or 42x, but external equipment such as a signal generator and a combiner may be required.

⁵ A test set with internal receiver attenuators is recommended to avoid receiver compression when measuring large input signals.

⁶ When ordering a test set, select an appropriate interface kit.

⁷ When configured as a multiport analyzer using S93551B and a multiport test set, the combiner feature of Option 22x or 42x is temporarily disabled. When configured as a standalone analyzer, the combiner feature is enabled.

⁸ PNA-X models only.
