Test Sets

Integrated RF communications test sets are designed to analyze transmitters, receivers, and transceiver components. They typically combine RF generators, audio analyzers, and power meters into a single chassis. Highly integrated benchtop units, such as the Keysight Technologies (Agilent HP) 8920B and Keysight Technologies (Agilent HP) 8920A, provide analog and digital testing for land mobile radios and paging systems, with the 8920B generating RF signals from 250 kHz to 1000 MHz. For PMR standard testing, the Aeroflex 3920 offers frequency coverage from 10 MHz to 2.7 GHz.

Multi-format instruments like the Rohde & Schwarz CMW500 and Rohde & Schwarz CMU200 support cellular protocol testing across standards like GSM, WCDMA, and CDMA2000. These systems utilize network and base-station emulation to establish a cellular link with a device under test. Similarly, the Keysight Technologies (Agilent HP) E5515C acts as a hardware platform to emulate cellular networks and run parametric tests via dedicated measurement applications.

When testing specific localized wireless standards, specialized test sets reduce physical complexity. The Keysight Technologies (Agilent HP) N4010A is a PC-controlled, faceless test set supporting 2.4 GHz and 5 GHz bands, specifically built for evaluating WLAN (802.11a/b/g/n), Bluetooth, and ZigBee (IEEE 802.15.4) devices. Dedicated testers like the Anritsu MT8852B focus exclusively on Bluetooth basic rate (BR), enhanced data rate (EDR), and low energy (LE) testing up to core specification v5.3.

For metropolitan area wireless protocols, the Keysight Technologies (Agilent HP) E6651A provides Mobile WiMAX (IEEE 802.16e-2005) base station emulation and parametric analysis. Signal generation in these test workflows is often aided by specialized vector signal generators like the Keysight Technologies (Agilent HP) N5182A-503, which covers a 250 kHz to 3 GHz range and delivers fast switching speeds for rapid test execution. For general spectrum monitoring and diagnostics, a portable RF spectrum analyzer such as the Tektronix 2711 offers frequency coverage from 9 kHz to 1.8 GHz.

Telecom network infrastructure requires dedicated testing tools to verify physical layers and protocol structures on high-speed copper and optical links. Handheld units provide portability for field maintenance while retaining laboratory accuracy:

• Keysight Technologies (Agilent HP) J2127A: A field-portable, multi-rate transmission tester that supports line rates up to 10 Gb/s (OC-192 / STM-64) for SONET/SDH, PDH/DSn, and Ethernet monitoring.
• Sun Sunset OCx: A handheld analyzer designed for electrical and optical network transmission testing up to OC-12 (622 Mbps). It maps electrical interfaces (such as DS1, DS3, and E1) to optical rates (OC-3 and OC-12).
• Sun Sunset T10: A specialized handheld T1 transmission test set that operates at 1.544 Mbps. It is designed to troubleshoot T1 circuits using AMI and B8ZS line coding, offering bit error rate testing (BERT) patterns like QRSS, 511, and 2047.

Network and impedance analyzers often require external test sets to route signals for multi-port transmission, reflection, or S-parameter measurements:

• Keysight Technologies (Agilent HP) 85047A and Keysight Technologies (Agilent HP) 85046A: Active 50 Ω S-parameter test sets for two-port devices. The 85046A covers 300 kHz to 3 GHz, while the 85047A extends up to 6 GHz. Both feature integrated bias tees to apply DC bias to the device under test.
• Keysight Technologies (Agilent HP) 8517B: A high-frequency S-parameter test set featuring a 4-channel architecture with 2.4 mm ports, operating from 45 MHz to 50 GHz.
• Keysight Technologies (Agilent HP) 41952A and Keysight Technologies (Agilent HP) 87512A: Passive transmission/reflection test sets. The 41952A operates up to 500 MHz, and the 87512A handles frequencies up to 2 GHz. These units require no external power supply.
• Keysight Technologies (Agilent HP) 43961A: An RF Impedance Test Kit that adds 1-port impedance measurement capabilities (such as |Z|, |Y|, Rp, and Rs) to compatible host analyzers up to 1.8 GHz.
• Keysight Technologies (Agilent HP) 85131F: A high-performance 3.5 mm flexible cable set operating up to 26.5 GHz, used to maintain phase and amplitude stability when connecting these network systems to devices under test.
