Signal Generator Overview

Modes of Operation

NOTE If the PSG’s dynamic host configuration protocol (DHCP) is enabled, the network assigns the instrument an IP address at power on. Because of this, when DHCP is enabled, the IP address may be different each time you turn on the instrument. DHCP does not affect the hostname.

12.Click Browse, and double- click the firmware revision to upgrade your signal generator.

13.In the Upgrade Assistant, click Next.

14.Once connection to the instrument is verified, click Next and follow the on- screen prompts.

NOTE Once the download starts, it cannot be aborted.

NOTE When the User Attention message appears, you must first cycle the instrument’s power, then click OK.

When the upgrade completes, the Upgrade Assistant displays a summary.

15. Click OK and close the Upgrade Assistant.

Modes of Operation

Depending on the model and installed options, the PSG signal generator provides up to four basic modes of operation: continuous wave (CW), swept signal, analog modulation, and digital modulation.

Continuous Wave

In this mode, the signal generator produces a continuous wave signal. The signal generator is set to a single frequency and power level. Both the E8257D and E8267D can produce a CW signal.

Swept Signal

In this mode, the signal generator sweeps over a range of frequencies and/or power levels. Both the E8257D and E8267D provide list and step sweep functionality. Option 007 adds analog ramp sweep functionality.

Analog Modulation

In this mode, the signal generator modulates a CW signal with an analog signal. The analog modulation types available depend on the installed options.

Option UNT provides amplitude, frequency, and phase modulations. Some of these modulations can be used together. Options UNU and UNW provide standard and narrow pulse modulation capability, respectively.
