# What's the difference between Wave Cycle Multiplier and Frequency Multiplier?

Entering a Frequency Multiplier will only change the value of the frequency. Entering a Wave Cycle Multiplier has no effect on the frequency value. Instead, it alters how Spooky2 constructs the waveform, and thus allows the generator to create frequencies higher than its built-in hardware limit.

It also allows Spooky2 to create complex waveforms like the damped sine/square and H-Bomb waveforms. Perhaps an example can help you understand.

Example 1

Lets say you have the following set:
CODE: SELECT ALL
10, 16, 24

If you choose a Frequency Multiplier = 2, the software will send a command to the Spooky2-XM to generate the following frequencies:
CODE: SELECT ALL
20, 32, 48

However, if instead we set the Wave Cycle Multiplier = 2, the software will download a waveform with 2 periods in it, and send the commands to the Spooky2-XM generator to generate the following frequencies:
CODE: SELECT ALL
5, 8, 12

When using the Wave Cycle Multiplier = 2, the software will show it generated 10, 16, 24, but the Spooky2-XM will show it generated 5, 8, 12.

Example 2

Using the 1st frequency set shown above, let's you wanted to generate the following frequency set: 10 Mhz, 16 Mhz, 24 Mhz (Mhz = million hertz).

One might try setting the Frequency Multiplier = 1000000 (1 Mhz), to get the desired set. However, the Spooky2-XM internal clock can only go to 5000000 (5 Mhz), so the software sends a command to the Spooky2-XM to generate the following frequencies:

CODE: SELECT ALL
5000000, 4000000, 3000000

which is 5 Mhz, 4 Mhz, 3 Mhz. These altered frequencies are the highest octal subharmonics under the 5 Mhz limit of the XM of your desired frequencies.

However, if you use the Wave Cycle Multiplier in conjunction with the Frequency multiplier = 1000000 (1 Mhz), and set the Wave Cycle Multiplier = 8, the software will send a command to the Spooky2-XM to generate the following frequencies:

CODE: SELECT ALL
1250000,2000000,3000000

When using the Wave Cycle Multiplier = 8, the software will show it generated 10 Mhz, 16 Mhz, 24Mhz, but the Spooky2-XM will show it generated 1.25 Mhz, 2 Mhz, 3 Mhz.
