Providing pure signals with low phase noise at all offset frequencies, a 6GHz instrument generates up to 38dBm RF output power, and a 20GHz instrument generates up to 32dBm in the microwave frequency range. Harmonics are low across the entire frequency range – above 6GHz they are lower than 70dBc at 18dBm output power. Nonharmonics are below 110dBc at an output signal of 1GHz.
"The SMA100B enables our customers to verify the true performance of their devices under test without the signal source affecting the results," says Andreas Pauly, vice president of signal generators, audio analysers and power metres.
In addition to delivering pure analogue RF signals, the generator can simultaneously provide a second, independently configurable, synchronised clock signal up to a frequency of 6GHz. As a result, users can characterise A/D converters with a single analogue signal generator.
The SMA100B is said to generate pulses with short rise and fall times and an on/off ratio of less than 90dB. Closed loop level control is available for pulse widths starting at 100ns. These characteristics make it possible to test advanced radar receivers under demanding pulse scenario conditions.
The SMA100B can provide high level signals with low, close-in phase noise (10GHz, -83dBc/Hz, 10Hz offset). The instrument's low phase noise option ensures that phase noise and wideband noise from simulated in-band or out-of-band interferers have a minimal impact on the wanted signal.
The high output power option enables the SMA100B to provide up to 38dBm of output power, eliminating the need for external amplifiers in automated test environments.
Wear-free electronic step attenuators are integrated. The SMA100B is designed for the RF semiconductor, wireless communications and aerospace and defence industries.
