This portable analyzer provides enhanced basic performance with high-precision, high-stability measurements, a minimum n 50us High-speed Sweep Function sweep width of 1kHz by means of a synthesized local oscillator, In Zero Span mode (fixed tuning mode without frequency and time domain measurements utilizing 50μs high-speed sweep), the sweep time can be set up to 50us. This makes it sweep. possible to observe TDMA waveforms for PDC and PHS, and to perform detailed analysis through magnified display of rising and falling burst waveforms.n The Lightest Spectrum Analyzer in Its Class at 8kg (Max.) n Variety of Measurement Functions The U3661 has a main unit mass of 8kg or less, easily portable 1Hz resolution counter, occupied frequency bandwidth, adja- for a microwave spectrum analyzer with a measurement fre- cent-channel leakage power, AM/FM audio monitoring, AM quency range from 9kHz to 26.5GHz. modulation measurement, reduced dB measurement, gated sweep. n Battery Provides 1.5 Hours of Operation. Three Power Sources to Choose From The U3661 operates not only on 100/200 VAC power but also on +10 to +16 VDC external power or on the battery pack; three- way power supply. It is designed to operate in any power source environment. The battery pack can be easily attached/ removed by a one-touch operation and rapidly recharged in one hour. It allows approximately 1.5 hour continuous opera- tion on a full recharge, enabling logistically wide-ranging operation such as maintenance/installation work. 122 Spectrum Analyzers Compact, Lightweight, 3-Way Power Source, 26.5GHz U3661 Specifications Frequency Range : 9 kHz to 26.5 GHz Band (N) 0(1) : 9 kHz to 3.2 GHz 1(1) : 3.0 GHz to 7.1 GHz 2(2) 6.7 GHz to 14.5 GHz 3(3) 4(4) 13.7 GHz to 26.5 GHz Accurracy : Freq readout × Fref Acc +5%Span + 15%RBW + 60 × N SPAN setting : 10 kHZ - 26.5 GHz Accurracy : ±5% RBW : 1 kHz to 3GHz (Opt. 100 Hz to 300 Hz) VBW : 1 Hz to 1 MHz (1-10 Step) C/N : -100 dBc/Hz+20LogN @ 10 kHz -105 dBc/Hz+20LogN @ 20 kHz -110 dBc/Hz+20LogN @ 100 kHz Residual FM : < (60 × N) Hz pp in100mS Drift : 150 Hz × N (Span<10 kHz) -6 -5 Reference : ±2 × 10 /Year Temperature ±1 × 10 Level Max level : +30 dBm Noise level Band 0 : -117 dBm + 2f(GHz) (1 MHz to) Band 1 : -112 dBm RBW 1 kHz Band 2 : -109 dBm ATT 0 dB Band 3 : VBW 10 Hz Band 4 : -100 dBm Display Range(LOG) : 100 dB Total accuracy Calibrator accuracy : ±0.3 dB @ -20 dBm RBW switching : ±1 dB Log linearity : ±1.5 (90 dB) Freq Response Band 0 : ±2 dB Band 1 : ±2 dB Band 2 : ±4 dB Band 3 : Band 4 : ±5 dB Gain compression : 1 dB -10 dBm f>10 MHz Spurios Response : Value/condition 2nd Distorsion : -70 dBc 10 MHz to 3.2 GHz(-30 dBm in) : -80 dBc (>3.2 GHz)(-30 dBm in) 3th Intermod : -70 dBc (-30 dBm in) Residual Response : -100 dBm 1 MHz to 3.2 GHz ATT0 dB -90 dBm 3.2 GHz to input term50 Sweep Sweep time : 50 ms to 1000 s 50 μs to 100 s SPAN 0 Sweep Trigger : Free run,/Single/Video/Ext./TV Function Diplay type : TFT Detector Trace Display Built-in function Display/nb,point : 701 General Temperature : 0 to 50 °C Power : <70 W Size : 148 (H) × 291 (W) × 330 (D) mm Mass : 8.3 kg 123
