The platform supports LTE FDD, W-CDMA/HSPA, GSM/GPRS/EGPRS, and CDMA2000 1X/1xEV-DO standards through a combination of installed signalling unit options and simulation software. A built-in high-end PC running Windows 7 Ultimate hosts the control software, eliminating the requirement for an external control computer in the test setup. The MD8475A is positioned for R&D evaluation of mobile handsets and modules that must operate across multiple global network standards. Documented use cases include testing triple-system LTE/W-CDMA/GSM/GPRS terminals, hybrid LTE/CDMA2000 terminals, packet communications and application performance, voice and video call behavior, SMS and MMS messaging, and handover and CS Fallback scenarios between LTE and legacy systems. The platform also supports access-class control and emergency call testing — scenarios that are difficult or impossible to evaluate on live networks. ValueTronics International maintains its inventory of complex signalling and protocol test instruments — including the MD8475A platform — in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. Cellular signalling testers carry significant configuration complexity: the installed signalling units, software licenses, and option strings determine which network standards and features a specific unit actually supports. Direct physical custody of inventory at our Elgin facility allows our technicians to verify installed options against listing descriptions before shipment, rather than relying on prior-owner representations or drop-ship pass-through. For an instrument family where the difference between two units of the same model number can be tens of thousands of dollars in installed software value, that verification step is the substantive difference between a documented professional purchase and an unverified marketplace transaction. ## Brand Heritage Anritsu Corporation is a Japanese precision measurement company with roots extending to 1895. The North American RF and microwave product portfolio relevant to the MD8475A's heritage was significantly shaped by Anritsu's 1993 acquisition of Wiltron Company. Anritsu remains an independent public company headquartered in Atsugi, Kanagawa, Japan. ## Accessories Supplied - MX847500A Platform Software (factory-installed) - MX847501A Control Software (factory-installed) - Power Cord - MD8475A CD-ROM (Operation Manual) - P0035B W-CDMA/GSM Test USIM (Standard UICC Size) - J1440A LAN Cable (3 m) - Z0541A USB Mouse - Z0975A Keyboard (USB) - A0058A Handset ## Product Core & Specifications Parameter Specification RF Connector RF input/output connector (RF Main, RF Aux1, RF Aux2) Connector: N type, Impedance: 50 Ω, VSWR: ≤1.5 (500 MHz to 3 GHz) Reference oscillator Frequency 10 MHz Reference oscillator Level TTL level Reference oscillator Connector BNC type Startup characteristics ±5 × 10\-8 (5 minutes after power-on, referenced to frequency 24 hours after power-on) Aging rate 2 × 10\-8/day, ≤1 × 10\-7/year (referenced to frequency 24 hours after power-on) Temperature characteristics ≤±2 × 10\-8 External reference input Frequency: 10 MHz, Acceptable frequency range: ±0.5 ppm, Level: ≥0 dBm, Impedance: 50 Ω, Connector: BNC type Transmission Characteristics Frequency range 350 MHz to 3.6 GHz Setting resolution 100 kHz (Depending on MX847501A used) Accuracy Based on reference oscillator accuracy Output level range −130 to −10 dBm (Main, Aux1, Aux2) Output level resolution 0.1 dB Level accuracy ±1.0 dB (−120 dBm ≤ Output level, 350 MHz ≤ Frequency ≤ 3 GHz); ±1.2 dB (−120 dBm ≤ Output level, 3 GHz < Frequency ≤ 3.6 GHz) Non-harmonic spurious ≤−40 dBc (at ≥500 kHz frequency offset) Harmonics ≤−25 dBc Modulation accuracy W-CDMA ≤3.5% rms (with MD8475A-010) Modulation accuracy GSM ≤1.5° rms (with MD8475A-020) Modulation accuracy LTE ≤3.5% rms (with MD8475A-050) Modulation accuracy CDMA2000 1X ρ >0.995 (with MD8475A-030) Modulation accuracy 1xEV-DO ρ >0.995 (with MD8475A-032) Reception Characteristics Frequency range 350 MHz to 3.6 GHz Setting resolution 100 kHz (Depending on MX847501A used) Maximum input level +35 dBm (Average) Input level range −60 to +35 dBm (with MD8475A-010, MD8475A-030, MD8475A-032, MD8475A-050); −30 to +40 dBm (in-burst average power) (with MD8475A-020) Reference level −60 to +35 dBm Rx level setting resolution 1 dB General Display Color TFT LCD screen, 12.1 inches (wide type), 1280 × 800 dots Trigger I/O BNC Call Proc Timing I/O 15-pin mini D-Sub connector Call Proc Serial I/O D-sub connector, RS-232C level Call Proc Ethernet A RJ45 connector, 10/100/1000BASE-T level Call Proc Ethernet B RJ45 connector, 10/100/1000BASE-T level Handset RJ-11 connector Headphone 3.5-mm dia. headphone jack Microphone 3.5-mm dia. microphone jack USB USB 2.0, Type A, 4 ports RS-232C D-sub connector, conforms to RS-232C GPIB IEEE 488 connector VGA Mini D-Sub connector Ethernet RJ-45 connector 10/100/1000BASE-T, 2 ports Power Supply 100 Vac to 120 Vac (±10%) / 200 Vac to 240 Vac (−15%/+10%, Max.: 250 Vac), 50 Hz to 60 Hz (Rating), ≤480 VA (Max.)

CDMA2000 testing does not use the Test USIM.**Important:** The MD8475A mainframe requires the appropriate Signalling Unit hardware (MD8475A-010 W-CDMA/HSPA, MD8475A-020 GSM, MD8475A-030 CDMA2000 1X, MD8475A-032 CDMA2000 1xEV-DO, and/or MD8475A-050 LTE) plus the matching Simulation Software license for each cellular system to be tested. The base mainframe alone does not perform signalling tests.**Important:** SmartStudio (MX847570A) operation requires the matching system license option (MX847570A-010 W-CDMA, -020 GSM, -030 CDMA2000, -050 LTE FDD) installed for each system to be tested.**Important:** 2-cell test environment requires both the MD8475A-001 2nd RF hardware option and the MX847502A Multi-cell Software. 2-cell testing is not supported for CDMA2000.**Important:** LTE 2x2 MIMO testing (MX847550A-020) requires the MD8475A-001 2nd RF hardware option. Handover tests are not supported when testing 2x2 MIMO.**Important:** MMS transmission/reception testing requires a separate MMS application server.**Important:** Test USIM is not used by CDMA2000.Recommended pairing: when configuring a two-cell or simultaneous dual-system test environment, the MD8475A-001 2nd RF hardware option must be combined with the MX847502A Multi-cell Software — both are required for inter-system handover, CS Fallback, and cell-reselection testing per the datasheet's 2-cell Test Environment description. ## About this used unit - Warranty included - Functional verification included - Standard Calibration Upgrade Options: No Calibration Required, NIST Traceable, Z540.1 or ISO 17025 with Data, Z540.3 Guardbanding with Data. - Note that unnecessary accessories may not be included (contact Test Architect to confirm). **Please review the Manufacturer's Data Sheet to verify published specifications.
