Example Display: A spectrum analysis screen showing signal amplitude over frequency, with controls for center frequency, span, and resolution bandwidth.
Excellent Sensitivity to Test Weaker Signals
The UTS1000B/T series offers excellent sensitivity, with a DANL as low as -161 dBm, making it ideal for testing weak signals that are easily affected by the analyzer's noise floor.
Example Display: A spectrum analysis screen showing a very low amplitude signal, demonstrating the analyzer's sensitivity with a DANL of -161 dBm.
Removable Dust Mesh
The instrument features a detachable dust filter that can be removed from the air inlet to prevent dust accumulation. This ensures the reliability of the machine and prevents potential issues like short-circuit, burn, or fire caused by dust.
Visual Description: The rear panel of the spectrum analyzer is shown, highlighting the air inlet with a dust mesh.
Scan 10,001 points
The UTS1000B/T series supports up to 10,001 sweep points, enabling higher frequency resolution and making it easier to capture difficult-to-detect signals.
Example Displays: Two spectrum analysis screens are shown, illustrating the difference in detail when using a higher number of sweep points.
Excellent Selectivity
The spectrum analyzer demonstrates a strong capability to resolve signals with adjacent unequal amplitudes.
Example Display: A spectrum analysis screen showing two closely spaced signals with different amplitudes, highlighting the analyzer's selectivity.
EMI Pre-compliance (Option)
With optional components and near-field probes, the UTS1000B/T series assists in locating and resolving EMI defects early in the development cycle.
Example Display: An EMI scan showing signal levels against frequency, with markers indicating compliance limits and measured values.
Advanced Measurement (Option)
The advanced measurement mode supports various transmitter test specifications, including Channel Power, T-power, Occupied BW, TOI, ACP, Spectrum Monitor, CNR, and Harmonics.
Example Display: A spectrum analyzer screen configured for advanced measurements, showing parameters like Channel Power and Occupied Bandwidth.

Definitions and Conditions
Specifications: Describe performance parameters covered by the product warranty, generally applicable within a temperature range of 20°C to 30°C unless otherwise noted.
Typical: Refers to product performance information not covered by the product warranty. 80% of units exhibit 95% confidence over the 20°C to 30°C range when performance is out of specification. Typical performance does not include measurement uncertainty.
Nominal Value: Represents expected performance or product performance useful in applications but not covered by the product warranty.
Operating Conditions: The analyzer meets specifications when within its calibration cycle and warmed up for at least 30 minutes. If stored outside the operating temperature range, it requires at least two hours of acclimatization within the allowable operating temperature range before use.
