2 Getting Started Before connecting and powering up the instrument, please review and go through the instructions in this chapter. 2.
1. Use good quality 50 Ω coaxial cable and connectors. 2. Make all connections tight and as short as possible. 3. Use good quality attenuators, if it is necessary to reduce waveform amplitudes applied to sensitive circuits. 4. Use termination or impedance-matching devices to avoid reflections. 5. Ensure that attenuators and terminations have adequate power handling capabilities. If there is a DC voltage across the output load, use a coupling capacitor in series with the load.

USB Interface The instrument has a USB interface (USBTMC) in the rear panel for remote communication with EasyWave software. Note: A type A to type B USB cable is required for PC connectivity. To connect with EasyWave software, you must install NI-VISA. NI-VISA is downloadable from LabVIEW™ website. There are no settings for USBTMC. Make sure to set the LAN State to OFF. Note: Users who have LabVIEW™ or NI-VISA installed will automatically have this driver in their system.

Either channel 1 or channel 2 can be the waveform this signal is synchronized with. Figure 66 - Sync Output Function Description Menu State Off Turn off the sync output.
Syncing Signals of Different Waveforms Basic Waveform and Arbitrary Waveform 1. When the frequency of the waveform is less than or equal to 10 MHz, the sync signal is a Pulse with approximately 50 ns pulse width and the same frequency as the waveform. 2. When the frequency of the waveform is greater than 10 MHz, there is no sync signal output. 3. Noise and DC waveforms will have no sync signal output. Modulated Waveform 4.
prompt message “No external clock source!” would be displayed and the clock source would be switched to “Internal”. 4. The unit can also output a 10 MHz clock signal when the 10MOut is enabled. If the output of the clock signal is enabled, then the [10MHz In/Out] connector in the rear panel will function as an clock signal output only.
