TSG4G1 is a very cost-effective USB RF signal generator. Its capabilities are comparable to the basic functions of a regular full-size RF signal generator. TSG4G1 is miniature and portable equipment, but it has more features and functions with a frequency range up to 4.4GHz, frequency sweep, frequency hopping, and pulse modulation.

You can configure this device to meet a wide variety of test tasks. TSG4G1 is very suitable for the field test because it is very small and convenient to carry. It can also work at ATE system as a module, being able to simulate a lot of RF systems for test purposes.

Choosing the TSG4G1

• The TSG4G1 is suited to applications that don’t need I&Q channel for generating modulation signals, and the frequency requirement is lower than 4.4GHz.
• The TSG4G1’s signal output is from an ADF4351, with the output level calibrated and controlled.
• The TSG4G1 can also work uncalibrated with a large output level (up to 16dBm at some frequency points).
• Spurious signals are less when the output frequency is between 700MHz and 4400MHz, so the TSG4G1 can work with a power meter to test S11 andS21 at this band.
• The TSG4G1 works with pulse modulation, frequency sweeping and hopping.
• The TSG4G1 also have an LF signal output and a pulse signal output for lower frequency applications.

Limitations with the TSG4G1

When the frequency is lower than 700MHz, more spurious signals will be apparent due to the ADF4351’s RF divider. A divider design cannot be used to achieve problem-free low frequencies, and other solutions are too costly for the targeted price point. Any RF signal generator using a ADF4351/ADF4355/RFMD2081 combination will have this problem.
