any individual harmonic.

SMPTE, DIN or CCIF Distortion

See System Specifications.

Sine Flatness

20 Hz to 20 kHz: ±0.05 dB.

l0 Hz to 163.8 kHz: ±0.2 dB.

Square wave Rise time

1.5 µs ±10%.

Burst Range

1 to 65535 cycles ON.

1 to 65535 cycles OFF.

OFF level either -20 dB or zero. All switching

at sine wave zero crossing. Triggered, gated,

or free-running burst modes available.

Output Level Range and Accuracy

Balanced:

open circuit: 200 µV to 21.2 V RMS.

into 600 Ω: -72.45 dBm to +28.05 dBm1.

Unbalanced:

open circuit: 200 µV to 10.6 V RMS

into 600 Ω: -72.45 dBm to +22.05 dBm1.

1Rs = 50 Ω. For maximum available output

from other impedances, subtract 1.25 dB

for Rs - 150 Ω and 5.35 dB for Rs = 600 Ω.

Resolution:

0.05 dB in dBm mode, typically 0.25%

or better in volts mode.

Level Accuracy (Sine wave):

20 Hz to 20 kHz ±2.0% (0.2 dB).

10 Hz to 163.8 kHz ±3.0 (0.3 dB).

Output Impedance and Configuration

50 Ω ±3%, 150 Ω ±2%, or 600 Ω ±1%,

balanced or unbalanced, floating or grounded.

External Input

A floating single-ended input is provided

for accessing the variable gain stage and

high level output amplifier, enabling the

use of custom test signals. Input

impedance is approximately 20 kΩ; a 2 V

RMS input (2.83 V peak maximum)

provides a calibrated output.
