Frequency Coverage and Port Configurations
The Lightning series models are primarily distinguished by their maximum operating frequencies to suit specific test applications. The Anritsu 37247D serves applications up to 20 GHz. For higher-frequency requirements, the Anritsu 37369A, Anritsu 37369C, and Anritsu 37369D operate up to 40 GHz. The broadest frequency coverage is provided by the Anritsu 37397C and Anritsu 37397D, which extend measurements up to 65 GHz.
Port connector types match these frequency demands. The 40 GHz models utilize 2.92 mm compatible K connectors, configured as male on the Anritsu 37369A and female on the Anritsu 37369D. The 65 GHz models utilize 1.85 mm compatible V connectors, with the Anritsu 37397C featuring male connectors and the Anritsu 37397D featuring female connectors.
Hardware Configurations and Interface Options
Hardware options and chassis designs evolved across the different generations of the Lightning series. The earlier Anritsu 37369A features a 7.5-inch active-matrix color LCD, two PCMCIA slots, and dual GPIB ports. Within the 37300C series, the Anritsu 37369C integrates a 3.5-inch MS-DOS compatible floppy disk drive, and the Anritsu 37397C features an 8.4-inch active-matrix color LCD, dual GPIB, and a PS/2 keyboard interface.
The D-series models introduce updated connectivity and integration. The Anritsu 37247D, Anritsu 37369D, and Anritsu 37397D feature 10BASE-T LAN interfaces alongside standard GPIB and serial ports. The Anritsu 37369D includes standard source and test port step attenuators, standard internal bias tees, and support for E/O and O/E measurements. The Anritsu 37397D provides internal storage consisting of both a hard disk drive and a 3.5-inch floppy drive.
Measurement Accuracy and Calibration Methods
All models in this series support high-resolution S-parameter measurements (S11, S21, S12, S22). The Anritsu 37369C offers a magnitude resolution of 0.001 dB and a phase resolution of 0.01°, with an averaging range from 1 to 4096. Calibration options also vary: the Anritsu 37369C supports SOLT, TRL, LRL, and LRM methods, while the Anritsu 37397D supports SOLT, LRL, LRM, TRM, and Offset Short calibration.
For advanced applications, the Anritsu 37247D and Anritsu 37369D standard software supports multiple source control, frequency offset modes, and E/O and O/E measurements. The Anritsu 37247D additionally includes an NxN Calibration Utility for mixer measurements and an embed/de-embed application.
