The latest generation of Anritsu handheld spectrum analyzers includes the MS2725C Spectrum Master. This high performance spectrum analyzer offers exciting new features and options, which bring more value to the user over our previous generations:

• Frequency Coverage - 9 kHz to 32 GHz
• Broadband preamplifiers over the whole frequency range for increased sensitivity around 20 dB
• Three Sweep Modes – with improved Sweep Speed - up to 100 times faster
• Resolution Bandwidths from 1 Hz to 10 MHz
• New triggering choices including hysteresis, hold-off, and delay
• More zero-span capabilities including 10 MHz RBW & VBW
• Enhanced Spectrum Analyzer GUI including large marker display choice
• Choice of display options for readability – normal, black and white, night vision, high contrast
• On-screen Interference Mapping as part of the Interference Analysis option
• LTE Measurements up to 20 MHz
• 30 MHz Wide Zero-Span IF Output at 140 MHz center frequency for external demodulation of virtually any other wideband signal

The Spectrum Master MS2725C features over 30 analyzers in one to meet virtually every measurement need. In addition to spectrum analysis a user can select optional capabilities and analyzers including:

• High Accuracy Power Meter
• Interference Analyzer
• Channel Scanner
• 140 MHz Zero-Span IF Output, 30 MHz bandwidth
• GPS Receiver
• Increased frequency accuracy, geo-tag data collection
