Marconi 6960/001 RF Power Meter, Like HP 437B THIS IS THE LAST ONE, MY FAVORITE. The 6960 Power Meter has a frequency range of 30kHz to 26.5GHz and a dynamic range of +20 dBm to -70 dBm. The accuracy is +/- 0.02 dB. The AUTOZERO function automatically zeros each of the instrument's five ranges and stores the data so that zero carry-over error is less than 0.03%. The AUTOCAL key automatically calibrates the instrument to an internal 50 MHz, 1 mW power reference. Typical response time is 250 ms for manual operation, with fastest response of 25 ms when using the GPIB interface. Response time and resolution can be automatically optimized for each range. In normal operation the instrument will 'auto-range'. Any range may be 'held', however, to facilitate 'peaking' adjustments. A 'max-hold' function allows only the maximum measured power value to be displayed. Manual control is through a calculator-type keypad, which allows rapid selection of instrument settings and entry of data. The main display is a large four-digit LCD with a variety of annunciators. An additional analog meter gives a display relative to the top of the current range. Ten non-volatile memories, which can each store complete instrument settings for up to ten years, further reduce test time and operator effort. Measurements can be displayed in either logarithmic (dBm) or linear (nW, uW, mW, W, kW) units. Offsets can be entered using the dB REL key to allow for attenuation or amplification of power, or to measure drift. For pulse systems, direct readings of peak pulse power can be made by entering the appropriate duty cycle. The automatic setting of response time/resolution can be overridden to increase resolution, giving maximum displayed resolution of 0.001 dB. A 'self-check' is performed at each power-up. Routine pre-measurement calibration is achieved by two key presses (AUTO ZERO and AUTO CAL). Tested and works good and all the functions work. 120 volt AC power cord included. Power Sensor and Cable are NOT included. They are for demonstration only. (please look at our rules and privacy policy) |
