Multi-touch HD Screen for Quick Operation
10.1-inch multi-touch HD capacitive screen with quick menu settings. Supports multiple gesture operations such as dragging, expanding, and zooming on the trace. Convenient human-computer interaction operation solves the problem of cumbersome and difficult operation to the greatest extent.
Excellent Sensitivity to Test Weaker Signals
The weak signal test is easily affected by the noise floor of the spectrum analyzer itself. UTS3000T+ series has a DANL as low as -161 dBm, providing excellent sensitivity to effectively test weak signals.
Removable Dust Mesh
With a detachable dust filter, after the instrument is used for a period of time, the user can remove the dust from the air inlet. To ensure the reliability of the whole machine, it can avoid short-circuit, burn or fire caused by dust.
Scan 10,001 points
UTS3000T+ series provides up to 10,001 sweep points, offering higher frequency resolution and making it easier to capture signals that are difficult to detect.
Excellent Selectivity
It has a stronger capability to resolve signals of adjacent unequal amplitudes.
EMI pre-compliance (Option)
UTS3000T+ series includes optional components that, when used with near-field probes, assist in locating and resolving EMI defects in advance, thereby shortening the development cycle.
Advanced measurement (Option)
The advanced measurement mode provides the test items required by the transmitter test specification: Channel Power, T-power, Occupied BW, TOI, ACP, Spectrum Monitor, CNR, and Harmonics.
Analog demodulation analysis (Option)
Provides AM, FM analog signal for demodulation analysis.
Definitions and Conditions
"Specifications" describes the performance of the parameters covered by the product warranty in detail, unless otherwise noted, these specifications apply to the temperature range of 20°C to 30°C.
"Typical" refers to other product performance information not covered by the product warranty. 80% of the units can exhibit 95% confidence over the temperature range of 20 °C to 30 °C when performance is out of specification. Typical performance does not include measurement uncertainty.
"Nominal Value" means expected performance, or describes product performance that is useful in product applications but not covered by the product warranty.
The analyzer can meet its specifications under the following conditions:
- It is within its calibration cycle and has warmed up for at least 30 minutes.
- If the analyzer has been stored within the allowable storage temperature range but outside the allowable operating temperature range, it must be placed within the allowable operating temperature range for at least two hours before starting.
