• 1 MHz to 1040 MHz Frequency Range • GPIB Programmability • 32 Complete Front-Panel Stored Settings • Nonvolatile Memory • Programmable Internal Modulation Source • 50 Watt Reverse Power Protection Model 3510B, a microprocessor- controlled Signal Generator, covers the frequency spectrum of 1 to 1040 MHz Standard features nclude a programmable internal audio source for AM and FM modulation, a nonvolatile memory and full GPIB programmability + 13 dBm Output; 0.001 % Frequency Accuracy RF output power range is +13dBm to - 137 dBm with flatness to ± 1 dB ( + 13 to -6,9 dBm). Frequency resolution is 100 Hz and accuracy is 0.001 % (typically 0.0002%). The standard stability of 0 2 ppm/hr may bp improved by using the optional External Reference input, the optional Internal/ External Reference and/or the optional High Stability Internal Reference. Modulation Flexibility The interna! modulation signal can bcatanylOHzincrement between 80 Hz and 10 kHz. This internal source may be combined with an external source to create complex or simultaneous modulation such as AMonFM.FMonFMor AM on AM. Simple Operation Manual control is via a 48-key touch pad front panel. A “beeper” indicates a button has been pressed. All settings are displayed. Output levels are conveniently read out in dBm or volts. Up to 32 complete front-pane settings may be stored in a nonvolatile memory and recalled to the front panel on command A unique cursor system has selectable increment sizes. A reference mode allows frequency or level references to be set; subseauent display values are relative to the reference value. All functions are GPIB programmable except power on/off. Programming is “free format." and multiple function changes can Pe executed simultaneously. Frequency switching and settling time over the bus is typically 75 ms.
