3403C Agilent Voltmeter

Additional Features:

• DC and 2 Hz to 100 MHz
• 3 1/2 Digit

Specifications:

Ranges

• Full range display: 10.00 mV (ac only); 100.0 mV; 1.000 V; 10.00 V; 100.0 V; 1000 V
• Overrange: >90% on all ranges except as limited by max input voltage
• Ranging information: front panel annunciators indicate overrange (approximately 190 % of full range), or underrange (approximately 17 % of full range) conditions

Performance:

AC Frequency Range

• Slow response: 2 Hz to 100 MHz
• Fast response: 25 Hz to 100 MHz
• Response Time Fast response: 1 s
• Slow response: 10 s; Instrument reads final reading ± 0.1% of input change in stated response time

Display Rate

• Fast response: 4 readings per s
• Slow response: 2 readings per s

Functions

• DC: responds to de component of input signal
• AC: responds to true rms value of ac coupled input signal
• AC+ DC: responds to true rms value of dc and ac input signal; reading is √(dc)² + (ac rms)²
• Temperature coefficient: ± (0.1 x reading accuracy/°C) outside the 25°C ± 5°C temperature range
• Accuracy: 90 days (25°C + 5°C, < 95% RH, 17% of range to 190 % of range)

Input Characteristics

• Input impedance: (< 10 MHz)
• 1 V to 1000 V range: 10 MΩ ± 10% shunted by 24 pf ± 10%
• 10 mV and 100 mV range: 20 MΩ ±l0% shunted by 20 pF ± 10%

Maximum Input Voltage

• High to low: 1000 V rms, 1500 peak or 10⁸ V-Hz on any range
• Maximum dc voltage in ac mode: 500 V dc
• Low to chassis:  ± 500 V dc, when floated with special banana to BNC adapter

General:

• Operating Conditions 
• Temperature range: 0°C to 50°C
• Humidity: <95% RH
• Power: 115 V or 230 V ± 10%, 48 Hz to 440 Hz, 35 VA max. (including all options) 
• Input terminals: BNC front panel connector standard for low to high terminals: rear panel connector available by internally reversing position of ac converter module

Recorder Output

• Output voltage: 1 V dc open circuit for full range input
• Output resistance: 1 kV =- 10%

The Model 3403C is usable from dc to 100 MHz. True rms is especially valuable for measurements of noise, multiplexed signals, modulated waves and signals with high harmonic content.

dB Display

The dB display option provides readings directly in dB, a major convenience to ac users. The dB reference to which the measurement is made is conveniently adjustable from the front panel to provide referenced dB measurements, or to provide a convenient means to offset the reading by as much as 13 dB for unreferenced measurements.
