Ultima calibração 2020Here is the Agilent / HP 8935 / E6380A unit. This unit was originally made for CDMA Base Station Testing but it makes an excellent Service Monitor. HP had 2 different types of 8935 units. One was the E6380A and it included CDMA Tests, the other is the E6381A and it includes TDMA Tests. It's a well built rugged design with an "electro-luminicent" display. The membrane type keyboard is helpful in restricting moisture from getting into the unit. The test connectors are all on the side of the unit. Althow not pictured, there is a cover to protect the front of the unit. This unit is similar but not exactly like the HP 8920B units. It includes similar features and screens like the : RF analyzer, AF Analyzer, RF Generator, Encoder, Decoder, Spectrum Analyzer / Tracking Generator. Also included is Power Meter, Sinad and Distortion meters, Full Duplex operation, AC/ DC Voltmeter, Self Diagnostic Tests, and Configure Screens. It has 2 AF generators useful for generating 1000Hz tone and CTCSS tones at the same time, 2 uV "off the air" sensitive receiver, AM, FM and SSB modes, 75 Watt continuous or 125 Watt intermittent power input, antenna, duplex and RF I/O ports. It will save and recall screen setups with its internal memory. It uses the more common PCMCIA SRAM cards to install / remove data.
