Used when the programmable calibrator's accuracy is not essential. * **4324 50 MHz (0 dBm) Power Reference Module:** (Rear Output) Functionally similar to the 4323. * **Optional Accessory Cables:** Available in lengths of 10 ft, 20 ft, 50 ft, and 100 ft, allowing sensors to be located up to 100 feet from the instrument.### Electrical Characteristics* **Power Consumption:** 40 VA. * **Input Voltage:** 100, 120, 220, 240 V ±10%, 50 - 400 Hz.### Interfaces* **IEEE-488 Bus:** Complies with IEEE-488 standards, implementing SH1, AH1, T6, L4, SR1, RL1, DC1, and DT1. The open SEAbus Plus Protocol enables communication with host PCs and other systems.### Physical Characteristics* **Dimensions:** 3.485 in (8.8 cm) high, 17.24 in (43.8 cm) wide, and 17.75 in (45.0 cm) deep. * **Weight:** 21 lbs (9.5 kg) with 6 channels and a programmable calibrator. * **Environmental Compliance:** Meets MIL-STD-28800D Type II, Class 5, Style E and F equipment standards. * **Operating Temperature:** 0°C to 55°C. * **Storage Temperature:** -55°C to +75°C.### Features and Functionality* **Channel Math:** Allows mathematical operations between all six channels. * **Zeroing:** Each range is independently zeroed via front panel or bus. * **Limits:** Front panel or bus selectable between +100 dB and -100 dB, independently for each channel. * **Filtering:** Selected by entering filter time in ms (20 ms to 20 s), accomplished in 20 ms increments (e.g., 2000 ms selects 100-point, pipeline averaging). * **Ranging:** Autoranging, set-ranging, and hold on range; each channel operates independently. Hold on range offers 10% headroom and 25 dB dynamic range per range (0.2 dB resolution at -25 dB point). * **Sensor Compatibility:** Compatible with all Boonton diode and thermocouple sensors. A wide selection of sensors are available to cover various frequency and power ranges. * **Duty Cycle Entry:** Supported for pulse power measurements. * **Upgradability:** Advanced system architecture supports simple upgrades of the meter's on-board operating software.### Compatibility* **Power Sensors:** Compatible with all Boonton diode and thermocouple sensors.
