|IFR 2023 Generator|
|Beschreibung:||AM/FM SIGNAL GENERATOR|
The 2023 and 2024 are portable and lightweight synthesized signal generators covering the frequency range 9 kHz to 1.2 GHz (2023) and 9 kHz to 2.4 GHz (2024). A dot matrix display with a comprehensive set of utility menus allow flexibility of operation and ease of use. The RF output can be amplitude, frequency, phase or pulse modulated. An internal programmable AF source is capable of generating simultaneous two-tone modulation. All parameters can be entered from a front panel keyboard and a rotary control can be used to adjust most settings. Microprocessor control ensures that the instruments are flexible and easy to use and allows programming by either the General Purpose Interface Bus (GPIB) or by RS-232. The GPIB is designed to IEEE Standard 488.2. The interfaces allow remote control of all functions except the supply switch, and allow the instruments to be used either manually or as part of a folly automated test system. Main features Operation Selection of parameters on the screen may involve one or more of the numeric, hard or menu selection keys or the rotary control knob. Parameters may be set to specific values by numeric key entry, while values may be varied in steps of any size using the DOWN/UP keys or altered by moving the control knob, set to a particular sensitivity. Display The display is a dot matrix liquid crystal panel, with backlighting. Display contrast may be varied to accommodate differing lighting conditions and the setting saved in memory. A graphical display test is available to the user. Frequency selection Carrier frequency is either selected directly via the keyboard or remotely via the interfaces. Frequency resolution is 1 Hz across the band. A series of carrier frequencies can be stored in non-volatile memory for recall when required. Output RF output up to +13 dBm can be set by direct keyboard entry with a resolution of 0.1 dB over the entire range. For instruments fitted with the high power option, RF output is increased to +25 dBm. A carrier ON/OFF key is provided to completely disable the output. A choice of level units is available to the user and provision is made for the conversion of units (for example, dBm to μΥ) by a simple keypress. An electronic trip protects the generator output against reverse power of up to 50 W. This prevents damage to output circuits when RF or DC power is accidentally applied to the RF OUTPUT connector. To facilitate testing of receiver squelch systems, an attenuator hold function allows control of the RF output without introducing RF level drop-outs from the step attenuator. The RF output level can be offset by up to ±5.0 dB to compensate for cable or switching losses, or standardize a group of instruments. Maximum RF output level can be set so as to protect sensitive devices connected to the RF OUTPUT socket.
