Need to select ALC hold when using RF blanking. Limit ALC Hold to no more than 100 ms, as the ALC Level may degrade. The hold selection remains until you reconfigure it, preset the signal generator, or cycle the signal generator power. Incorrect ALC settings can cause a sudden unleveled condition to occur. An unleveled RF output can damage a DUT or connected instrument. Ensure that you set markers such that the ALC obtains a sample that accounts for the high power levels within the signal. 7.

And every positive edge. A TRUE pulse at the Q output will be set to FALSE immediately on a negative edge. Undesirable connection of the IN input: If no further measures for exception avoidance are taken, the undesirable connection of the IN input to a signal not designated for this purpose will cause the signal connected in error to control pulse generation. As a result, the pulse generator will be restarted on every positive edge. A TRUE pulse at the Q output will be set to FALSE immediately on a negative edge. Impermissible static TRUE signal at the IN input (operating current principle): If no further measures for exception avoidance are taken, a static TRUE signal at the IN input will cause the pulse generator to run continuously and it will not be possible to stop it. Impermissible static FALSE signal at the IN input (closed-circuit current principle): If no further measures for exception avoidance are taken, a static FALSE signal at the IN input will cause the pulse generator to be idle continuously and it will not be possible to start it.

Each attenuator introduces errors. While you output extremely low amplitude signals, the internally-generated system noise of a signal generator becomes critical. The lower the system noise floor, the higher the signal-to-noise ratio (SNR). Lower SNR results in a poor receiver sensitivity measurement. In addition to the system noise floor, interfering signals can be a source of errors for extremely low amplitude signals. To resolve the errors, place the device under test (DUT) in a shielded environment. Beyond the Output Range RF signal generators are capable of outputting as high as +25 dBm and as low as -120 dBm. If you need to go beyond the specified range, you can use an amplifier to increase the output power or an attenuator to decrease it. When you extend the output range of the signal generator, there are some important factors to be aware of. Amplifier gain uncertainty affects the output amplitude level Attenuator’s flatness and accuracy performance Tips for Optimizing Amplitude Accuracy There are several ways to optimize amplitude accuracy while you use an external amplifier or an attenuator (or other passive accessories) with a signal generator. The common method is to use a vector network analyzer (VNA) to measure the entire signal path and enter correction values into the signal generator. Below are 2 tips to improve amplitude accuracy easily by using the built-in capabilities of new signal generators. Tip 1: Using Flatness Correction User flatness correction allows the digital adjustment of RF output amplitude to compensate for external losses in cables, switches, or other devices. By using power meter/sensor to calibrate the measurement system, a table of power level corrections can automatically be created. The USB power sensor connects to the signal generator directly. The signal generator works as a power meter and measures the power at the test plane. The correction values can be saved in the signal generator’s memory and you can recall and apply the correction values the next time you use the same test configuration. Figure 2 below illustrates the flatness correction setup by using a signal generator and USB power sensor. Figure 2: Flatness correction by using USB power sensor Tip 2: Using External Leveling External leveling lets you move the ALC feedback source closer to the DUT so that it accounts for most of the power uncertainties inherent to the cabling and components in a test setup. Figure 3: Test setup for external leveling As the RF power level at the input of the power coupler/splitter changes, the external detector returns a compensating negative voltage. The ALC circuit uses this negative voltage to level the RF output power by raising or lowering the signal generator’s power. This ensures a constant power level at the.
