A wide range of user features, including duty cycle, rel- ative power measurements and limit checking make the 6970 Power Meter highly versatile. The same wide range of power sensors used with the IFR 6960 PowerMeters and the 6200B series Microwave Test Set are used by the 6970. Field and Bench Use The 6970 is designed for both field and bench use. For the installa- tion and maintenance engineer the instrument replaces large and expensive meters with no loss of measurement performance. Rechargeable batteries mean that there is no need for an AC supply; this greatly eases measurements at remote sites such as an antenna tower. Additional benefits of the 6970 are lower cost and portability. An optional soft carrying pouch with both belt loop and shoulder strap enable the 6970 to be easily carried in field environments For bench operation the instrument takes up little bench space and it can be powered from the AC adapter. Battery operation is ideal for field operation High Accuracy The 6900 series power sensors all have an excellent return loss spec- ification to minimise mismatch errors in power measurements. Correction for power sensor frequency response and high power non-linearity is also provided by entry of calibration factor and lin- earity factor values into the 6970. issue 7.qxd 03/12/04 10:58 Page 1 RadioFans.CN 收音机爱 好者资料库 All the power sensors are individually calibrated and supplied with a calibration data chart. The auto ZERO function reduces offset errors on each of the 6970 ranges. This increases measurement accuracy at low power levels and improves the measurement sensitivity. Built-In Power Reference The built-in power reference provides an accurate 0 dBm (1 mW) 50 MHz calibration signal. Power sensors can be calibrated against this reference for improved measurement accuracy and traceability. The power reference is automatically switched on during a CAL pro- cedure or it can be enabled at any time to provide a traceable 0 dBm signal for verification. Operation The instrument front panel consists of a keyboard and a four digit LCD with annunciators. Power levels are clearly displayed on a digi- tal readout with an analog bargraph to facilitate peaking and nulling. Power levels may either be displayed in logarithmic units such as dBm or dBV or in Watts. To save battery life, the unit powers down six minutes after the last key press. 6970 will operate for 7 hours from a full battery charge. When the instrument powers down the last operator set-up is stored and this will be the state the 6970 assumes when it is next switched on. Upper and lower power limits can be set. An audio and visual alarm alerts the user of a measurement that is out of limits. This is useful to set a power to a pre-determined level as well as for monitor-ing purposes. The 6970 is fully auto-ranging but manual range hold is also possible. Manual range selection is used when measuring modulated or unsta- ble signals. The display indicates either AUTO or MAN as appropri- ate and will also provide information of over/under-range conditions. Wide Range of Power Sensors The 6970 uses the same rugged IFR power sensors that have been developed for the 6960 Power Meter and 6200B series Microwave Test Set. A wide range of 17 sensors is available covering the frequencies from 30 kHz to 46 GHz. Power level measured depends on sensor type, sensors cover from -70 dBm (0.1 nW) to +44 dBm (25 W). To cater for the different frequency ranges connector types include N type, PC 3.5 mm, 2.92 mm and N type (75 W).
