For the very latest specifications visit www.aeroflex.com Carryover ±0.03% of FSD (when zeroed on most sensitive range). Drift ±0.1% of FSD (±2% 6920 series) on range 1 (most sensitive) over 1 hour at constant temperature after 24 hour stabilization. Decrease by factor 10 for each higher range. NOISE Less than 1% of FSD (2% for 6920 series) for most sensitive range with an average factor greater than 19. OUTPUTS (BNC socket) Fast levelling 0 to 1 V each range, 1 kÙ impedance, excludes correction for Cal Factor, Linearity Factor and Average Number. (For external levelling of RF source.) Recorder ±1%. dB mode: 1 V/decade, 7 V maximum on range 5. Watts mode: 5 V linear. Fully corrected for Cal Factor, Linearity Factor and Average Number (For plots of the full 50 dB dynamic range). Blanking Maximum voltage: 25 V Maximum current: 50 mA, open collector, short circuit for blank. RESPONSE TIME Range 1 (most sensitive) 1 s, selectable. Ranges 2 to 5 250 ms (display update), selectable 25 ms using GPIB. GENERAL GPIB INTERFACE GPIB unit built into instrument if option 001 is ordered. All front panel functions are remotely programmable except for test modes. KEY FUNCTIONS Units Selects either linear (mW) or logarithmic (dBm) units with toggle action. dB Rel Displays current offset which may be entered in range -99 to +99 dB. Store & Recall Stores up to 9 complete instrument settings for any set-up condition (eg Cal Factors at different frequencies); store 0 contains instrument settings prior to last power down. Max Hold Retains maximum reading of changing signal. When enabled, units annunciators flash. Range Displays current range in use; ‘Au’ denotes auto ranging, ‘Hd’ indicates held range. Any range may be selected and held at any time. Averaging Enables any integer number in the range 1 to 256 to be set. In Auto Averaging mode the following response times are obtained: Range Average No. Response Time 5 1 0.25 s 4 1 0.25 s 3 4 1 s 2 20 5 s 1 50 12.5 s Power Up Displays power-up mode currently in use. In power-up mode 1, instrument assumes default settings. Power-up mode 2 reinstates the settings in use at power down. Linearity Factor Provides data entry for individual sensor linearity data to improve accuracy. Duty Cycle Enables entry of duty cycle of pulsed signal in range 100% to 0.001%. The 6960B calculates the peak value of the pulsed signal from the average power measured by the sensor. ‘Peak’ annunciator displayed when duty cycle <100%. Calibration Factor Allows entry of sensor calibration factor in range 100% to 0.001 %. Local Returns instrument to ‘local’ front panel operation when remotely addressed unless ‘local lock out’ is employed. In manual operation, displays current GPIB address. Auto Zero Initiates zero routines to store zero offset for each of the 5 ranges. Auto Cal Initiates self-calibration routine after connection of sensor to Power Reference. Power Ref Toggles internal 0 dBm (50 MHz) power reference on and off. Resolution Resolution may be changed by altering the Average Number in the following format:- Range Resolution (dB) 0.1 0.01 0.001 Average Number 5 (highest power) 1 4 4 4 1 1 4 3 1 1 4 2 1 4 20 1 (lowest power) 4 20 50 ENVIRONMENTAL Operating Temperature 0°C to 55°C. Storage Temperature –40°C to +70°C. Storage Humidity Up to 95% relative humidity at 35°C. Altitude Up to 2500 m (pressurized freight at 27 kPa differential, i.e. 3.9 Ib/in2). ELECTROMAGNETIC COMPATIBILITY Conforms with the protection requirements of the EEC Council Directive 89/336/EEC. Conforms with the limits specified in the following standards: IEC/EN61326-1 : 1997, RF Emission Class B, Immunity Table 1, Performance Criteria B SAFETY Conforms with the safety requirements of EEC Council Directive 73/23/EEC (as amended) and the product safety standard IEC/EN 61010-1 : 2001 + C1 : 2002 + C2 : 2003 for class 1 portable equipment, for use in a Pollution Degree 2 environment. The instrument is designed to be operated from an Installation Category 2 or 1 and 2 supply.
