It ships as a standard configuration with 12 RF input ports, with 24 RF input ports available via Option 424. A high-speed switch inside the monitor provides measurement capability for each RF input, and greater than 30 dB of isolation is provided between each RF input port to assure the integrity of the measurement. The MS27103A is typically used with three- or six-sector BTS architectures, with multiple carriers per sector. Its measurement set covers occupied bandwidth and channel power, and its interference-analysis capabilities include spectrogram and signal strength. IQ block mode and streaming with time stamping support time difference of arrival (TDOA) applications, and the integrated GPS receiver supports monitoring location and time-synchronization applications. ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. Holding inventory directly in our own facility lets us manage condition, configuration, and fulfillment under one roof. ## Product Core & Specifications Specification Value Frequency Frequency Range 9 kHz to 6 GHz (tunable to 0 Hz) Tuning Resolution 1 Hz Frequency Reference Accuracy ±1.5 ppm (25 °C ± 25 °C) ±1.0 ppm/year aging; < ±50 ppb with GPS on Frequency Span 10 Hz to 6 GHz Sweep Speed, Typical (full span FFT mode), 10 kHz RBW 5 GHz/s Sweep Speed, Typical (full span FFT mode), 30 kHz RBW 12 GHz/s Sweep Speed, Typical (full span FFT mode), 3 MHz RBW 24 GHz/s Bandwidth Resolution Bandwidth (RBW) 10 Hz to 3 MHz in 1–3 sequence (–3 dB bandwidth) Video Bandwidth (VBW) 10 Hz to 3 MHz in 1–3 sequence (–3 dB bandwidth) (auto or manually selectable) Spectral Purity SSB Phase Noise @ 1 GHz, 10 kHz offset (–98 dBc/Hz) SSB Phase Noise @ 1 GHz, 100 kHz offset (–98 dBc/Hz) Amplitude Ranges Dynamic Range (> 106 dB) (2.4 GHz), 2/3 (TOI-DANL) in 1 Hz RBW Measurement Range DANL to Maximum Continuous Input Reference Level Range –150 dBm to +30 dBm Attenuator Range 0 dB to 50 dB in 5 dB steps Amplitude Units Log Scale Modes: dBm, dBµV Displayed Average Noise Level (DANL), RBW normalized to 1 Hz, 0 dB attenuation (Port 1 specified; other ports typical, within 1 dB) 10 MHz to 3.3 GHz (Preamp Off, Ref Level –20 dBm) Port 1: –140 dBm; Typical: –145 dBm \> 3.3 GHz to 4.1 GHz (Preamp Off, Ref Level –20 dBm) Port 1: –133 dBm; Typical: –138 dBm \> 4.1 GHz to 5 GHz (Preamp Off, Ref Level –20 dBm) Port 1: –130 dBm; Typical: –135 dBm \> 5 GHz to 6 GHz (Preamp Off, Ref Level –20 dBm) Port 1: –115 dBm; Typical: –123 dBm 10 MHz to 3.3 GHz (Preamp On, Ref Level –50 dBm) Port 1: –157 dBm; Typical: –160 dBm \> 3.3 GHz to 4.1 GHz (Preamp On, Ref Level –50 dBm) Port 1: –152 dBm; Typical: –155 dBm \> 4.1 GHz to 5 GHz (Preamp On, Ref Level –50 dBm) Port 1: –148 dBm; Typical: –152 dBm \> 5 GHz to 6 GHz (Preamp On, Ref Level –50 dBm) Port 1: –133 dBm; Typical: –141 dBm Spurs, Typical Residual Spurious (RF input terminated, 0 dB attenuation, preamp off), 10 MHz to 4.5 GHz (< –80 dBm) Residual Spurious (preamp off), > 4.5 GHz to 6.0 GHz (< –70 dBm) Residual Spurious (preamp on), 10 MHz to 5.0 GHz (< –95 dBm) Residual Spurious (preamp on), 16 MHz to 18 MHz (< –88 dBm) Residual Spurious (preamp on), > 5.0 GHz to 6.0 GHz (< –85 dBm) Input-Related Spurious < –60 dBc, 0 dB attenuation, –30 dBm input, carrier offset > 5 MHz Second Harmonic Distortion (Typical; 0 dB attenuation, –30 dBm input), 50 MHz (–50 dBc) Second Harmonic Distortion, > 50 MHz to 200 MHz < –60 dBc Second Harmonic Distortion, > 200 MHz to 3000 MHz < –60 dBc Third-Order Intercept (TOI) (Typical; preamp off, –20 dBm tones 100 kHz apart, 0 dB attenuation, ref level –20 dBm), 800 MHz (+7 dBm) TOI, 2400 MHz (+17 dBm) TOI, 200 to 2200 MHz +10 dBm TOI, > 2.2 GHz to 5.0 GHz +8 dBm TOI, > 5.0 GHz to 6.0 GHz +14 dBm Maximum Continuous Input 100 MHz to 6 GHz, ≥ 10 dB attenuation +22 dBm, ±50 VDC (for lower frequencies, derate max continuous input by 4 dB per decade) 300 kHz to 6 GHz, < 10 dB attenuation +10 dBm, ±50 VDC 9 kHz to 6 GHz, preamp on –10 dBm, ±50 VDC Amplitude Accuracy, Option 424 (24 Ports), k = 2 Port 1, 9 kHz to 5 GHz ±2.5 dB Port 1, > 5 GHz to 6 GHz ±3.0 dB Ports 2 to 12 (typical), 9 kHz to 5 GHz ±3.0 dB Ports 2 to 12 (typical), > 5 GHz to 6 GHz ±3.5 dB Ports 13 to 24 (typical), 9 kHz to 5 GHz ±3.0 dB Ports 13 to 24 (typical), > 5 GHz to 6 GHz ±3.5 dB Input VSWR < 2.5:1 typical Signal Processing Data Types I/Q time series: 8, 10, 16 or 24 bit resolution; Spectrum trace: 100 to 4000 points Data Transfer Modes I/Q time series or spectrum trace in streaming or block mode I/Q Data Streaming Rate Gapless on 100Base-T network, up to 2.6 MHz signal bandwidth I/Q Data Time Stamp Resolution 8.7 ns Antenna Port Isolation (Typical), ≤ 3 GHz \> 40 dB Antenna Port Isolation (Typical), > 3 GHz \> 30 dB General Specifications Internal Trace/Setup Memory 4 GB internal memory available for storing files RF In 12 SMA(f) ports, 50 Ω (24 SMA(f) ports, 50 Ω optional) External Power 11 W, ±20 VDC to ±70 VDC (110/220 VAC optional) Ethernet One RJ45 connector for Gbit LAN, 2nd port optional for daisy chain USB Two USB Type A connectors External Reference In 10 MHz, +10 dBm max, +5 VDC max, BNC(f) GPS SMA(f) Environmental MIL-PRF-28800F Class 3 Operating Temperature Range 0 °C to 50 °C Storage Temperature Range –40 °C to 71 °C Maximum Relative Humidity 95 % RH at 30 °C, non-condensing Vibration, Sinusoidal 5 Hz to 55 Hz Vibration, Random 10 Hz to 500 Hz Half Sine Shock 30 gn Altitude 4600 meters, operating and non-operating ESD, RF Input Pin Withstands up to ±4 kV Size 480 mm x 90 mm x 300 mm (18.9 in x 3.5 in x 11.8 in) Weight, 12-port 3.9 kg (8.9 lb) Weight, 24-port 4.5 kg (9.9 lb) Warranty Standard three-year warranty > **Important:** Maximum continuous input: +22 dBm, ±50 VDC (100 MHz to 6 GHz, ≥10 dB attenuation).
