Available Features (NB-IoT)

89601BHTC (89601B-BHT) NB-IoT Modulation Analysis provides the following NB-IoT signal modulation analysis capabilities:

Support for downlink and uplink signals
Standard-based presets for In-band (same PCI), In-band (different PCI), Guard Band and Standalone operation modes
Recorded demo signals for familiarization with the measurement and the NB-IoT standard.
Autodetection of Cell ID and Power Boosts
Power-based autodetection of NPDSCH or NPUSCH and grouping into a single user allocation
Separate measurement results and display for signals and user channels: NRS, NPSS, NSSS, NPRS, NPBCH, NPDCCH, and NPDSCH for downlink; NPUSCH and NPRACH for uplink
Decoded channel information for NPBCH, NPDSCH (single user), and NPUSCH
Measurement offset and interval (similar to time gating) used to select specific data intervals for analysis. Measurement offset and interval specified in slots+symbols
Analysis start boundary specified as Frame, Half-frame, Subframe, Slot, or Two Frames
Synchronization to NPSS (downlink), or NPUSCH-DMRS/NPRACH (uplink)
3GPP EVM Error vector magnitude (EVM): A quality metric in digital communication systems. See the EVM metric in the Error Summary Table topic in each demodulator for more information on how EVM is calculated for that modulation format. Minimization supported: amplitude, frequency, timing, and IQ Offset (uplink only)
Definable power boosts for uplink and downlink channels/signals
Adjustable symbol FFT Fast Fourier Transform: A mathematical operation performed on a time-domain signal to yield the individual spectral components that constitute the signal. See Spectrum. locations and EVM window length for OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. symbols
Frequency-domain displays, such as IQ measured, IQ reference, and error vector traces
Mirrored frequency spectrums can be flipped to remove the effects of high-side mixing
Averaging available for a variety of trace data and most numeric error summary, frame summary, and MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas. info table data:
- rms (video) - computes an rms average from the specified number of measurement sweeps
- rms (video) exponential - similar to rms (video) except that averaging continues past the average count with an exponential weighting
- continuous peak hold - holds the peak value of all the sweeps
