SRTC Test Report for FCC ID SRQ-MF296C
Report Number: SRTC2022-9004(F)-22080401(C)
Testing Center: The State Radio_monitoring_center Testing Center (SRTC)
This document presents the results of radio frequency testing conducted by The State Radio_monitoring_center Testing Center (SRTC) for the device identified by FCC ID: SRQ-MF296C. The tests cover spectrum analysis, spurious emissions, and band edge compliance.
Complementary Cumulative Distribution Function (CCDF) Plots
This section presents Complementary Cumulative Distribution Function (CCDF) plots, which illustrate the distribution of signal power and help assess the peak-to-average power ratio (PAPR) or crest factor. These plots are generated for various carrier frequencies and bandwidths, showing the probability of a signal amplitude exceeding a given level. Common parameters displayed for each plot include:
- Ref Level: Reference Level (dBm)
- Att: Attenuation (dB)
- Offset: Offset (dB)
- SGL Count: Signal Count
- AQT: Acquisition Time (ms)
- RBW: Resolution Bandwidth (MHz)
- CF: Center Frequency (GHz)
- Mean: Mean Power (dBm)
- Peak: Peak Power (dBm)
- Crest: Crest Factor (dB)
- 10%, 1%: Probability levels for power exceedance (dB)
- 0.1%, 0.01%: Probability levels for power exceedance (dB)
- Samples: Number of samples recorded
- Date: Date of test
The following figures present CCDF plots for various frequencies, including but not limited to 1.715 GHz, 1.755 GHz, 1.775 GHz, 1.7175 GHz, 1.7725 GHz, 1.72 GHz, and 1.77 GHz. Each figure corresponds to a specific test configuration and frequency band.

Spurious Emissions at Antenna Terminal
This section details the conducted spurious emissions measured at the antenna terminal of the device. The data is presented in a table followed by corresponding spectrum plots.
Band | Carrier frequency (MHz) | Channel | BW | RB Size | RB Offset | Conducted Spurious Plot |
---|---|---|---|---|---|---|
