Options

Option 010 (High Stability Time Base)

Option 011 (HP-IB interface)

Option 020 (Digital Voltmeter)

Option 021 (High Performance Digital Voltmeter)

Option 030 (Channel C - measurements to 512 MHz)

Option 031 (Channel C - measurements to 1300 MHz)

Option 040 (High Performance Universal Module)

Option 050 (Combination of options 020 & 031)

Burst and CW measurements to 100 Mhz. Special gating circuits start a measurement only when an input signal is present, allowing burst frequencies to be measured as easily as CW signals.

Single shot time interval measurements: 100 ns single shot resolution

Display: 9 digit LED display. The ninth digit is only used with channel C functions (i.e. FREQ C, RATIO C/A, Events C, A->B.

Blanking feature supresses display of unwanted zeros to left of most significant digit

Storage: holds reading between samples, can be overwritten by read panel switch.

Sample rate is variable from less than 2ms between measurements to HOLD which holds display indefinitely.

Gate output: rear panel output, TTL levels, high if gate is open

Period, period average, ratio, totalize, scale features.

Trigger lights blink when channel is triggering. The light is on when input is above trigger level. This simplifies trigger level adjustments.

Approx. weight: 20 lbs

Approx. size: 16.75" W x 3.5" H x 17.5" D (includes knob clearance)
