Phase Error Less than 1° above 10Hz
Orthogonality 90° ± 1°
Demodulator
Stability 5 ppm/°C on LOW dynamic reserve
50 ppm/°C on NORM dynamic reserve
500 ppm/°C on HIGH dynamic reserve
Time Constants Pre: 1msec to 100 sec (6 dB/Octave)
Post: 1sec, 0.1 sec, none (6 dB/Octave) or none
Offset Up to 1X full scale (10X on expand)
Both channels may be offset
Harmonic Rej -55 dB (bandpass filter in)
Outputs & Interfaces
Channel 1 Outputs X (RcosØ), X Offset, R (magnitude), R
Offset, X Noise, X5 (external D/A)
Channel 2 Outputs Y (RsinØ), Y Offset, Ø (phase shift of
signal), Y Noise, X6 (external D/A)
Output Meters 2% Precision mirrored analog meter
Output LCD's Four digit auto-ranging LCD display shows same
values as the analog meters
Output BNC's ±10 V output corresponds to full scale input,
<1Ω output impedance
X Output X (RcosØ), ±10 V full scale, < 1Ω output impedance
Y Output Y (RsinØ), ±10 V full scale, < 1Ω output impedance
Reference LCD Four digit LCD display for reference phase
shift or frequency
RS232 Interface controls all functions. Baud rates from 300
to 19.2 K
GPIB Interface controls all functions. ( IEEE-488 Std )
A/D 4 BNC inputs with 13 bit resolution (±10.24 V)
D/A 2 BNC outputs with 13 bit resolution (±10.24 V)
Ratio Ratio output equals 10X Channel 1 output divided by
the Denominator input.
